Изобретение относитс к области получени лакокрасочных композиций и может быть использовано при отделке кож.The invention relates to the field of making paints and varnishes and can be used in leather finishing.
Дл закреплени покрывного сло отделанной кожи в кожевенной области промышленности широко примен ют нитролаки , содержащие в качестве пленкообразуюндего полимера нитрат целлюлозы, пластификатор и растворители с разбавител ми типа бутилацетата и этилового спирта . For fixing the coating layer of the trimmed leather in the leather industry, nitrolacs are widely used, containing cellulose nitrate as a film-forming polymer, a plasticizer, and solvents with diluents such as butyl acetate and ethyl alcohol.
Однако покрыти на основе нитролаков недостаточно светостойки, склонны к старению в услови х эксплуатации, нитролаковые композиции легко воспламенимы.However, nitrolak-based coatings are not sufficiently lightfast, prone to aging under operating conditions, and nitrolak compositions are easily flammable.
Наиболее близким но технической сущности к изобретению вл етс состав дл отделки хромовых кож на основе триацетата целлюлозы, пластификаторов (например, дибутилфталата) и хлорсодержащих органических растворителей (хлороформа и тетрахлорэтана ) 2.The closest to the technical essence of the invention is a composition for the finishing of chrome skins based on cellulose triacetate, plasticizers (e.g. dibutyl phthalate) and chlorine-containing organic solvents (chloroform and tetrachloroethane) 2.
Однако известна лакова композици не обеспечивает нолучение лаковой пленки,обладающей хорошей адгезией и светостойкостью .However, the known lacquer composition does not provide an acquisition of a lacquer film with good adhesion and light fastness.
Цель изобретени - повышение светостойкости и адгезии лаковой пленки.The purpose of the invention is to increase the light fastness and adhesion of the varnish film.
Поставленна цель достигаетс тем, что лакова композици дл отделки хромовых кож, включающа пленкообразующее на The goal is achieved by the fact that the lacquer composition for finishing chrome leathers, including film-forming on

Лаковую композицию готов т растворением при перемешивании пленкообразующего полимера - ацетата N-этилфениламинооксипропилового эфира целлюлозы (содерлсание азота 2,56%, св занной уксусной кислоты - 44,2%) или ацетата N-метилфениламинооксинропилового эфира целлюлозы (содержание азота - 1,37%, содержание св занной уксусной кислоты - 50,3%) в смеси растворителей и разбавителей с пластификатором.The lacquer composition is prepared by dissolving, with stirring, a film-forming polymer — N-ethylphenylamino-oxypropyl ether cellulose acetate (nitrogen content 2.56%, bound acetic acid — 44.2%) or cellulose N-methylphenylaminoinopropyl acetate (nitrogen content 1.37%, bound acetic acid content (50.3%) in a mixture of solvents and diluents with a plasticizer.
Составы предлагаемой композиции приведены в табл. 1.The compositions of the proposed composition are given in table. one.

Лакова композици бесцветна, прозрачна , стабильна во времени, не воспламен етс нри контакте с открытым пламенем. Композицию нанос т распылением на хромовые кожи после покрывного крашени вThe lacquer composition is colorless, transparent, stable over time, does not ignite when in contact with an open flame. The composition is applied by spraying onto the chromic skins after the coating dye.
