PURPOSE:To obtain the titled composition suitable for homogeneous tiles of vinyl chloride type or for dry care system, having excellent adhesivity, durability, dust resistance and proper gloss, by copolymerizing an amide monomer with an ethylene unsaturated carboxylic acid in a specific ratio. CONSTITUTION:The aimed high-quality composition which is obtained by polymerizing (A) 75-98wt.% monomer [e.g. one consisting of 20-95wt.% acrylic acid ester and/or methacrylic acid ester and 0-8wt.% styrene] with 2-25wt.% sum of (B) ethylenic unsaturated carboxylic acid and (C) acrylamide and/or methacrylamide in the ratio of the component B/C of 0.20/0.80-0.95/0.05 and has 20-80 deg.C glass transition temperature, 0.05-0.25mu average particle diameter range, 80,000-350,000 weight-average molecular weight and balanced resistance, adhesivity, dust resistance and gloss.
