A member for vehicle according to the present invention includes a resinous substrate, and a protective film being formed on a surface of the resinous substrate partially at least. The protective film is made by curing a curing-type coating-agent composition containing: Component (A) (e.g., an isocyanuric ring-containing urethane (meth)acrylate compound) in an amount of from 20 to 80 parts by mass; Component (B) (e.g., an isocyanuric ring-containing tri(meth)acrylate compound free from any urethane bond) in an amount of from 10 to 70 parts by mass; Component (C) (e.g., a reaction product) between a colloidal silica and an alkoxysilane compound having a maleimide group) in amount of from 1 to 35 parts by mass; a radical-polymerization initiator serving as Component (D) in an amount of from 0.1 to 10 parts by mass; an ultraviolet absorber serving as Component (E) in an amount of from 1 to 12 parts by mass; and an organic solvent serving 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. Said protective film demonstrates excellent wear resistance and weatherability. |

1. A member for vehicle, the member being characterized in that:
the member comprises a resinous substrate, and a protective film being formed on a surface of the resinous substrate partially at least; said protective film is made by curing a curing-type coating-agent composition containing:
following Component (A) in an amount of from 20 to 80 parts by mass;following Component (B) in an amount of from 10 to 70 parts by mass;following Component (C) in an amount of from 1 to 35 parts by mass;a radical-polymerization initiator serving as Component (D) in an amount of from 0.1 to 10 parts by mass;an ultraviolet absorber serving as Component (E) in an amount of from 1 to 12 parts by mass; andan organic solvent serving 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. Component (A): an isocyanuric ring-containing urethane (meth)acrylate compound being expressed by following General Formula (1); (In General Formula (1), each of R1, R2 and R3 expresses a divalent organic group whose number of carbon atoms is from 2 to 10 independently; and each of R4, R5 and R6 expresses a hydrogen atom, or a methyl group independently.); Component (B): an isocyanuric ring-containing tri(meth)acrylate compound being free from any urethane bond that is expressed by following General Formula (2); (In General Formula (2), each of R7, R8 and R9 expresses a divalent organic group whose number of carbon atoms is from 2 to 10 independently; each of R10, R11 and R12 expresses a hydrogen atom, or a methyl group independently; each of n1, n2 and n3 expresses a number of from 1 to 3 independently; and n1+n2+n3=from 3 to 9.); Component (C): an involatile component in reaction products being made by reacting an alkoxysilane compound (c1), which is expressed by following General Formula (3), with a colloidal silica (c2), in a mass ratio of from 9:1 to 1:9 between (c1) and (c2), the involatile component involving those in which (c2) is modified chemically with (c1); (In General Formula (3), R13 expresses a hydrogen atom, or a monovalent organic group; R14 expresses a divalent hydrocarbon whose number of carbon atoms is from 1 to 6; and “z” expresses a positive number of from 0.1 or more to 3 or less; moreover, when “z” is less than 3, the alkoxysilane compound (c1) involves a condensate, and R13 within a molecule in the condensate may even involve two or more types of distinct groups.) |
