Member for vehicle and manufacturing process for the same

A manufacturing process for a member for a vehicle excellent in terms of weatherability and wear resistance, the manufacturing process comprising:

• preparing a curable coating-agent composition containing:
• Component (A) in an amount of from 20 to 80 parts by mass;
• Component (B) in an amount of from 10 to 70 parts by mass;
• Component (C) in an amount of from 1 to 35 parts by mass;
• a radical-polymerization initiator as Component (D) in an amount of from 0.1 to 10 parts by mass;
• an ultraviolet absorber as Component (E) in an amount of from 1 to 12 parts by mass;
• and
• an organic solvent as Component (F) in an amount of from 10 to 1,000 parts by mass;
• with respect to a sum of the Component (A), the Component (B) and the Component (C) being taken as 100 parts by mass;
• applying said curable coating-agent composition onto at least a part of a surface of a resinous substrate;
• and
• curing said curable coating-agent composition, thereby forming a protective film on the surface of said resinous substrate:
• wherein Component (A) is an isocyanuric ring-containing urethane (meth)acrylate compound being expressed by the following Formula (1):
• in Formula (1), each of R1, R2 and R3 is a divalent organic group whose number of carbon atoms is from 2 to 10 independently;
• and each of R4, R5 and R6 is a hydrogen atom, or a methyl group independently;
• wherein Component (B) is an isocyanuric ring-containing tri(meth)acrylate compound being free from any urethane bond that is expressed by the following Formula (2):
• in Formula (2), each of R7, R8 and R9 is a divalent organic group whose number of carbon atoms is from 2 to 10 independently;
• each of R10, R11 and R12 is a hydrogen atom, or a methyl group independently;
• each of n1, n2 and n3 is a number of from 1 to 3 independently;
• and n1+n2+n3=from 3 to 9;
• and
• wherein Component (C) is an involatile component formed by reacting an alkoxysilane compound (c1) having Formula (3), with a colloidal silica (c2), wherein a mass ratio of (c1) to (c2) is from 9:1 to 1:9:
• in Formula (3), each R13 is independently a hydrogen atom, or a monovalent organic group;
• R14 is a divalent hydrocarbon whose number of carbon atoms is from 1 to 6;
• and “z” is a positive number of from 0.1 to 3;
• wherein, when “z” is less than 3, the alkoxysilane compound (c1) is a condensate.
