PURPOSE:To prepare a colored aggregate improved in resistances to solvent, water, heat, weather, abrasion and staining by compounding a specified one-pack type curable resin with an org. or inorg. colored pigment and an inorg. granular aggregate. CONSTITUTION:A one-pack type curable resin (A) having a C-C main chain and having NCO groups and hydrolyzable group-contg. silyl groups on its side chains is prepad. by copolymerizing 0.5-20% mol unsatd. isocyanate (a), 0.25-30% mol unsatd. silane (b) substd. by hydrolyzable group and a vinyl monomer (c) in the presence of a radical initiator in an org. solvent. Then the ingredient (A) is mixed with an org. or inorg. colored pigment and an inorg. granular aggregate. |
