HYBRID LATEX EMULSIONS AND COATING COMPOSITIONS COMPRISING HYBRID LATEX EMULSIONS Russian patent published in 2018 - IPC C09D5/00 C09D183/00 C08F220/00 

FIELD: chemistry.

SUBSTANCE: invention relates to coating compositions for coating a package. Coating composition comprises a hybrid latex emulsion obtained by mixing an ethylenically unsaturated monomer component and a stabiliser in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form a hybrid latex emulsion. Ethylenically unsaturated monomer component contains an organosilane compound which can include a reactive group and a hydrolysable inorganic alkoxysilane and an ethylenically unsaturated monomer that is not an organosilane compound. Hybrid latex emulsion has a gel content of more than 50 wt%. Method for coating a substrate by applying a coating composition to a substrate and a substrate coated with a coating composition are also described.

EFFECT: technical result is good resistance to clouding, resistance to abrasion, resistance to bubble formation, hardness and scratch resistance.
