Abstract
The present invention provides a plastisol composition which combines low temperature baking property and storage stability which are comparable to those of the prior polyvinyl chloride plastisols and has a low-temperature flexibility.The plastisol composition according to the present invention comprises an acrylic plastisol consisting of a plasticizer having acrylic resin particles and a filler dispersed therein and therewith formulated a blocked urethane prepolymer wherein free isocyanate groups of a terminal isocyanate containing urethane prepolymers have been blocked or a blocked polyisocyanate compound and a latent curing agent which is particulate solid at normal temperature, has a melt point of 60° C. or higher, and is insoluble in the plasticizer at 40° C. or lower.
