AQUEOUS DISPERSION OF A PEELABLE COATING COMPOSITION

摘要

THE AQUEOUS DISPERSION OF A PEELABLE COATING COMPOSITION OF THE PRESENT INVENTION IS (A) A MIXTURE CONTAINING 5-40BY WEIGHT OF AN EMULSION OF AN ACRYLIC COPOLYMER HAVING A GLASS TRANSITION TEMPERATURE ( HEREINAFTER REFERRED TO AS "TG" ) OF NOT LOWER THAN 40 °C , AND 95-60BY WEIGHT OF AN EMULSION OF ANOTHER ACRYLIC COPOLYMER HAVING A TG RANGING FROM -20 °C THROUGH 5°C. THE ACRYLIC COPOLYMER EMULSION MIXTURE (B) CONTAINS ETHYLENICALLY UNSATURATED VINYL MONOMERS HAVING ACID VALUE IN A TOTAL AMOUNT OF 0 . 5-1 . 0BY WEIGHT, AND (C) AT LEAST ONE OF THE ACRYLIC COPOLYMER EMULSIONS IS AN ACRYLIC COPOLYMER WHICH HAS BEEN POLYMERIZED BY USE OF A REACTIVE SURFACTANT, AND (D) THE PARTICLE SIZE OF THE ACRYLIC COPOLYMER EMULSIONS IS NOT MORE THAN 200 NM.
