2. Description of the Related Art Hitherto, those containing titanium dioxide as a white pigment have been mainly used for concealing so-called morphological troubles such as wrinkles, pores and roughness of skin caused by makeup cosmetics.

However, while such a titanium dioxide makeup cosmetic is effective against color tone troubles such as spots and freckles, it is not so effective against morphological troubles, and conversely makes troubles noticeable. Sometimes.
In addition, since it is thick, a natural finish cannot be obtained, which is often a problem.

On the other hand, as a method of concealing the form trouble,
Cosmetics containing various diffuse reflection type powders are known (JP-A-60-228406). However, it is difficult for these powders to maintain their effect on the skin for a long time, and when physically rubbed with clothes or hands, the powder falls off the skin, and the effect is halved. I have a problem.

A sample of an adhesive substance is applied to a release paper, dried, and attached to a coated paper, and then the release paper is peeled off to obtain an adhesive tape, which is kept at room temperature (25 ° C). ) And perform the test according to the following method.

(Test method) Tack: Tack according to the test method specified in JIS Z-0237 Adhesive force: Adhesive force according to the 180 degree peeling method specified in JIS Z-0237 (g / 25 mm) (Adherend: Stainless plate)

As a concrete example of such an adhesive substance,
Polymers obtained by copolymerizing an acrylic acid ester as a main component monomer with a polymerizable carboxylic acid (hereinafter referred to as an acrylic copolymer); three-dimensional reticulated silicone and the like can be mentioned.

[0012] Explaining these tacky substances in more detail, first, an acrylic copolymer is obtained by copolymerizing 1 to 10% by weight of a polymerizable carboxylic acid with an acrylic ester, and its average molecular weight is 10,000-10
It is about 0,000.

Examples of the acrylic acid ester include methyl acrylate, ethyl acrylate, propyl acrylate,
Examples thereof include butyl acrylate, isobutyl acrylate, hexyl acrylate, and 2-ethylhexyl acrylate. These can be used alone or in combination of two or more.

Examples of the polymerizable carboxylic acid include unsaturated carboxylic acids having a low carbon number, preferably acrylic acid, methacrylic acid, itaconic acid, maleic acid and the like. These can be used alone or in combination of two or more.

In addition to the acrylic ester which is the main component monomer, one or more of vinyl acetate, methyl methacrylate, and acrylamide may be used as the sub-component monomer. Similarly to the above, a polymer having an average molecular weight of 10,000 to 1,000,000 obtained by copolymerizing a main component monomer and a subcomponent monomer with 1 to 10% by weight of a polymerizable carboxylic acid based on the total amount of these monomers is used. In this case, the weight ratio of the main component monomer and the sub-component monomer is 99: 1 to 7
It is preferably 0:30.
