PEINTURES DURCISSABLES PAR ELECTRONS A BASE DE PARTICULES DE CAOUTCHOUCAMELIORE

摘要

A radiation-curable paint which on a pigment and particulate filler-free basis consists essentially of vinyl monomers and a unique, alpha-beta olefinically unsaturated, rubber-comprising resin formed by reacting a monohydroxy, monocarboxy terminated polyester with an acyl chloride to provide alpha-beta olefinic unsaturation and reacting the resultant alpha-beta olefinically unsaturated, monocarboxy terminated polyester with an epoxy-functional, graded-rubber particle. The dispersion is applied to substrates as a paint film and cured thereon by exposure to ionizing radiation, e.g., an electron beam.
