摘要

PPROBLEM TO BE SOLVED: To provide a structure for a stainproof road, which does not contain an organic metal in a coated film, which makes a finished appearance uniform and proper, without making a difference between the appearance skin of a recoated thick-film portion and that of a thin-film one, and which is superior in antifouling properties. PSOLUTION: In this structure for the stainproof road, an antifouling layer composed of an antifouling paint is formed on its surface. The antifouling paint contains a binder resin (A), a curing agent (B), a partially-replaced compound (C), and an acrylic block copolymer (D). The partially-substituted compound (C), in which water tolerance to acetone is 300% or more, consists of either or both of a compound (C-1) expressed by formula (1), RSP1/SPSBn/SBSi(ORSP2/SP)SB4-n/SB, and its partially-hydrolyzed condensate, and a compound (C-2) expressed by formula (2), HO(CHRSP3/SPCHSB2/SBO)SBn/SBRSP4/SP. In formula (1), RSP1/SPrepresents a 1-8C organic group; RSP2/SPrepresents 1-5C alkyl group; and n represents an integer of 0 or 1. In formula (2), RSP3/SPrepresents a methyl group or a hydrogen atom; RSP4/SPrepresents a 1-40C organic group; and n represents an integer of 2-30. PCOPYRIGHT: (C)2009,JPO&INPIT
