PROBLEM TO BE SOLVED: To obtain the subject composition having excellent maintenance with time, capable of improving unevenness of coating at a very small part, by compounding a specific acrylic core/shell resin with glycerol. SOLUTION: One or more selected from (A) A core/shell resin having (i) a core part comprising a copolymer consisting essentially of a methacrylic acid alkyl ester in which an alkyl is 1-4C (preferably methyl acrylate) and an acrylic acid alkyl ester in which an alkyl is 1-6C (preferably 2-ethylhexyl acrylate) and (ii) a shell part comprising a copolymer consisting essentially of styrene, a 1-4Cα-alkylstyrene (preferablyα-methylstyrene), a 1-4C acrylic acid alkyl ester (preferably butyl acrylate) and acrylic acid and/or its salt and (B) a core/shell resin having the core part (i) and (iii) a shell part comprising a copolymer consisting essentially of an acrylic acid alkyl ester in which an alkyl is 1-4C and acrylic acid and/or its salt is compounded with glycerol in the weight ratio of 1:1.5 to 1:3.
