COMPLETE SPECIFICATION STANDARD PATENT Application Number: Lodged: 0 0 0 00 0* 0 0# 00 Invention Title: ANTISTATIC CARD The following statement Is a full description of this invention, including the best method of performing It known to us 0 0e00 0* 00 0 0000 00 0 00 1 ANTISTATIC CARD Description The present invention relates to antistatic cards such as, for example, credit cards or telephone cards, which cards may carry magnetic strips and/or an electronic chip.
Most of the cards currently on the market are made of polyester or of polyvinyl chloride (PVC).
10 It is very desirable for these cards to be e C antistatic.
Indeed, static electricity is generated during their manufacture and their use, for example during printing or during installation of the magnetic 15 strips or else by rubbing in the readers. This gives.
rise to an accumulation of dust on the card, which is a nuisance to its manufacture, its printing and its operation. The usual additives do not form a stable mixture with the card material; exudation and loss of the antistatic effects may occur.
It has now been found that cards could be made using antistatic mixtures.
The present invention relates to cards based on a mixture: a) of at least one thermoplastic elastomer .laselected from the group consisting of: 0 polyester elastomers made of polyether diols, dicarboxylic acids and short chain diols; copolyether imide esters made of polyether diamines, tricarboxylic compounds or carboxylic anhydrides containing a carboxylic group, a dicarboxylic acid and a short chain diol; and 0 polymers having polyether diols and polyamide blocks; and at least one thermoplastic resin chosen from styrene resins, vinyl chloride resins, polycarbonates, polyesters and polyamides.
to. 9,
I
In the sense of the present invention, the term "cards" refers to credit cards, telephone cards, badges, car park entry cards, multiple-use underground railway tickets and, in general, anything with a thickness of 0.1 to 3 mm and which may measure, for example, from 1 cm in width by 2 cm in length to 5 cm in width by 20 cm in length.
S. The elastomer may comprise various 0 polyether blocks, and at least some of these blocks should be hydrophilic. Polyethylene glycol (PEG) is ee preferred as a hydrophilic group.
The thermoplastic elastomer may comprise polyether units and'polyester units. These are, for example, polyether blocks and polyester blocks.
99.. These products are known under the name 9 elastomeric polyesters, and are thermoplastic.
S. 20 The polyethers are, for example, polyethylene glycol, polypropylene glycol (PPG) or polytetramethylene glycol (PTMG). Some PEG must be present.
The molecular weight Mn of these polyethers may be between 250 and 6000.
These polyethers condense with at least one dicarboxylic acid in order to form the flexible segments of the elastomeric polyesters.
SThe polyester blocks result, for example, g from the condensation of at least one diol with at least one dicarboxylic acid. The diol may be glycol, propanediol or butanediol. The diacid may be terephthalic acid. These blocks form the hard segments of the elastomeric polyester.
The hard segments may comprise several units resulting from the action of a diol on a diacid.
The flexible segments may comprise several units resulting from the action of the polyether on a diacid. The hard segments and the flexible segments are attached together by ester linkages. Such elastomeric polyesters are described in patents EP 402,883 and EP 405,227.
The thermoplastic elastomers containing polyether units may also be ester copolyether imides.
The flexible segments are formed by the reaction of polyether diamines with tricarboxylic compounds or carboxylic anhydrides containing a carboxylic group, e.
such as, for example, trimellitic anhydride. The 20 polyether diamines used have an average molecular weight of 600 to 12,000. These polyether diamines may themselves be derived from polyethylene glycol, polypropylene glycol or polytetramethylene glycol, provided that polyether diamines derived from PEG are present.
The polyester blocks forming the segments in ester copolyether imides result, for example, from the condensation of at least one diol with at least one 4 dicarboxylic acid. The diol may be glycol, propanediol or butanediol. The diacid may be terephthalic acid.
Such ester copolyether imides are described in EP 402,883 and EP 405,227.
As regards the thermoplastic elastomers (a) which comprise polyether units and amide units, they may be distributed in a random or ordered manner. The amide units may be isolated or grouped in oligomers originating from the reaction of a diamine with a diacid or from the condensation of an alpha omega aminocarboxylic acid.
The elastomers most frequently used are those comprising polyamide blocks and polyether blocks. The polyamide blocks may originate either from the condensation of a lactam or of an alpha omega amino acid, or from the reaction of a diacid and a diamine.
SThese polyamide blocks may be prepared in the presence of a diacid. Polyamide blocks containing carboxylic acid end groups are obtained. The molecular weight Mn of the polyamide blocks may be between 600 and 5000.
The polyethers are, for example, polyethylene glycol, polypropylene glycol or polytetramethylene glycol of molecular weight Mn between 250 and 6000; several polyethers may be linked together, for example, by diacids in the case of the polyether diols, provided that PEG is present.
It would not be departing from the scope of
I---I
the invention to use other elastomers containing polyamide blocks and polyether blocks. These products may be prepared by reaction of lactam or alpha omega amino acid from diacid and polyether diol or polyether diamine. It is also possible to condense polyamide blocks containing amino end groups with polyether diacids, and to condense polyamide blocks containing acidic end groups with polyether diamines.
All these products are described in US Patents 4,331,786 4,115,475 4,195,015 4,839,441 and 4,864,014.
The styrene resins may be chosen from: polystyrene or mixtures thereof with polybutadiene, NBR (rubber/nitrile/butadiene) or block copolymers such as SBS (styrene/butadiene/styrene) or SEBS (styrene/ethylene-butylene/styrene), SIS (styrene/isoprene/styrene).
5. SAN (styrene/acrylonitrile) copolymers, ABS (acrylonitrile/butadiene/styrene) e 0* copolymers, MABS (methyl methacrylate/acrylonitrile/butadiene/styrene) copolymers, *e MBS (methyl methacrylate/butadiene/styrene) copolymers.
ABS, MBS and MABS may also be mixed with NBR, SBS, SIS or SEBS.
The thermoplastic resin may also be a I- polymer based on vinyl chloride, such as PVC. The PVC may be plasticized.
The thermoplastic resin may also be a polycarbonate. The polycarbonate may be aromatic or aliphatic or aliphatic-aromatic. In general, it is a homo- or copolymer of a bisphenol such as a 2,2-bis(4hydroxyphenyl)alkane, bis(4-hydroxyphenyl) ether or bis(4-hydroxyphenyl) sulphone, sulphide or sulphoxide.
The resin may also be chosen from polyesters such as, for example, PET (polyethylene terephthalate) or PBT (polybutylene terephthalate).
The resin may also be a polyamide.
The term polyamide resin currently refers to a resin produced by polycondensation of one or more amino acids such as aminocaproic acid, 7-aminoheptanoic acid or 11-aminoundecanoic acid, or polycondensation of equimolar amounts of a saturated dicarboxylic acid containing from 4 to 12 carbon atoms with a diamine, the diamine containing from 4 to 14 carbon atoms. An 4 4.
20 excess of diamine may be used, so as to obtain an excess of amine end groups relative to the carboxyl end groups in the polyamide.
By way of illustration of such resins, mention will be made of: polyhexamethyleneadipamide (polyamide 6-6), polyhexamethyleneazelaamide (polyamide 4 44 polyhexamethylenesebacamide (polyamide
'I
6-10), polyhexamethylenedodecanediamide (nylon 6-12), polyundecanoamide (polyamide 11).
It is also possible to use, in the present invention, polyamides prepared by polycondensation of at least two of the monomers mentioned above, thereby leading to copolyamides.
The polyamide resins of the present invention may also be produced by polymerization of one or more lactams such as caprolactam, which leads to polyamide 6, or lauryllactam, which leads to polyamide 12.
In the sense of the present invention, the term polyamide resin refers also to alloys of polyamides and polyolefins, containing polyamides in the majority. The polyolefins may be homo- or copolymers of ethylene or of propylene. These a9 9 alloys may comprise a compatibilizing agent.
The mixture of and may also comprise 20 common anti-UV, antioxidant, etc. additives.
The mixture is prepared by the usual methods of thermoplastics technology.
The cards of the invention may be S. manufactured by pressing, calendering, moulding, and the like. They may be formed of several sheets bonded or pressed together, between which magnetic strips or chips or electronic circuits have been inserted. In the latter case, the sheets have been partially hollowed 8 out such that a cavity has been made in order to accommodate the chip or the electronic circuit. In general, the card is produced directly as a sheet based on a mixture of and This sheet may be partially hollowed out on a part of its surface in order to receive therein a chip or an electronic circuit.
It is also possible to place magnetic strips on the surface of the card.
The amount of is determined by the desired degree of antistaticity and by the amount of hydrophilic polyethers contained in The elastomers available industrially contain from 10 to 20 by weight of hydrophilic polyether blocks. The Applicant has found that by using not more than 15 parts of per 100 parts of an antistatic effect was obtained from 4 to 12 parts of per 100 parts of are usually used.
o* S 20 The mixtures of the polymers and are very stable; there is no migration of A lasting antistatic effect is obtained. Unlike the case for the addition of carbon black in order to obtain an antistatic effect, the elastomers are colourless.
In particular, the amide block polyethers are totally colourless.
Unlike the case for certain antistatic agents, the elastomer is not corrosive towards 9 chips or electronic circuits.
The cards of the invention have a matt and silky appearance.
The cards of the invention may be printed on or decorated by any usual method. An exceptional sharpness of the characters and the images is observed.
It would not be departing from the scope of the invention to coat these cards, before or after the magnetic strips have been introduced, with one or more films made of thermoplastic resin.
Example: A mixture of ABS (92 parts) and amide block polyethers (8 parts) was prepared.
The elastomer is a polymer having PA6 blocks with an Mn -f 1500 and PEG blocks with an Mn of 1000 and a Shore D hardness Credit card-sized sheets 1.2 mm in thickness and with a hollow 8 mm in diameter and 0.4 mm deep were then prepared. Next, magnetic strips were placed on the non-hollowed-out side and these cards were then printed on. The chip was then installed No defect in the printing or in operation of the chip occurred. However, in a card which was identical but manufactured with resin alone, printing defects occurred since the printing chain became blocked on account of the static electricity or 06 since there was a large amount of dust present which interfered with printing and chips were destroyed by
