Zusammenfassung:To provide a coating layer that can be made further thinner and has improved slipperiness and wear resistance, a composition suitable for a coating capable of forming the coating layer, and a laminate comprising the coating layer.SOLUTION: A composition comprises ultra-high-molecular-weight olefinic polymer particulates (A) satisfying the following requirements (i)-(iii) and a solvent dispersible resin (B): (i) an intrinsic viscosity [η] of 5-50 dl/g as measured in a 135°C decalin solvent; (ii) an average particle size d50 of 3-45 μm in a mass-based particle size distribution by the Coulter counter method; (iii) 50 mass% or more of the particulates passable through a mesh sieve with an opening of 45 μm.SELECTED DRAWING: None 【課題】更なる薄膜化が可能であるとともに、優れた滑り性および耐摩耗性を有する塗膜、該塗膜を形成することができる塗料に好適な組成物、および該塗膜を有する積層体を提供すること。【解決手段】下記要件(i)~(iii)を満たす超高分子量オレフィン系重合体微粒子(A)と、溶媒分散性樹脂(B)とを含有する組成物:(i)135℃デカリン溶媒中で測定した極限粘度[η]が5~50dl/gの範囲にある;(ii)コールターカウンター法による質量基準粒度分布における平均粒子径d50が3~45μmの範囲にある;(iii)目開き45μmメッシュ篩を50質量%以上が通過する。【選択図】なし
