Abstract:
A silica composition, including: compound (A) represented by the following general formula (1); and acryl- or methacryl-modified silica particles (B): where X —  represents a halogen ion or a methyl sulfate ion, R 1  to R 4  each independently represent a hydrocarbon group having 1 to 36 carbon atoms, a hydrocarbon group having 1 to 36 carbon atoms that has any one or more kinds of substituents selected from an ester group, an amide group, and a hydroxyl group, or a polyether group represented by the following general formula (2), provided that at least one of R 1  to R 4  needs to represent a polyether group represented by the following general formula (2): R 5 —O m H   ( 2 ) where m represents a number of from 1 to 100 and R 5  represents an alkylene group having 2 to 4 carbon atoms, useful as an additive for a resin composition.

Claim (Index 9):
A method for improving scratch resistance of automotive paint, comprising adding to the automotive paint a resin composition comprising a reaction product of a silica composition and a vinyl group-containing monomer,\n the silica composition comprising: compound (A) of the following formula (1); and acryl- or methacryl-modified silica particles (B): where X \u2014  is a halogen ion or a methyl sulfate ion, R 1  to R 4  each independently are a hydrocarbon group having 1 to 36 carbon atoms, a hydrocarbon group having 1 to 36 carbon atoms that has any one or more substituents selected from the group consisting of an ester group, an amide group, and a hydroxyl group, or a polyether group of the following formula (2), provided that at least one of le to R 4  must be a polyether group of the following formula (2):\n \ue8a0R 5 \u2014O\ue8a0 m H \u2003\u2003(2) \n where m is a number of from 1 to 100 and R 5  is an alkylene group having 2 to 4 carbon atoms, and\n wherein compound (A) is contained in an amount of from 2 to 10 parts by mass with respect to 10 parts by mass of a raw silica particle, and \n wherein the acryl- or methacryl-modified silica particles (B) are obtained by reacting a hydroxyl group present on a surface of the raw silica particle with an isocyanate group of a modifier of the following formula (3), a cationic group of a modifier of the following formula (5) or a combination thereof: \n where R 6  is a hydrogen atom or a methyl group and R 7  is an alkylene group having 1 to 6 carbon atoms; where R 13  and R 15  each are an alkyl group having 1 to 4 carbon atoms, R 16  is an alkylene group having 1 to 6 carbon atoms, R 17  is a hydrogen atom or a methyl group, A is an oxygen atom or \u2014NH\u2014, and X is a halogen atom or a methyl sulfate derivative.
