Zusammenfassung:	To obtain a coating agent having excellent coating film strength without causing breakage or cracks when coated and stretched on a substrate film and further to obtain a laminate containing a substrate film layer and a coating agent.SOLUTION: There is provided a coating agent containing a 4-methyl-1-pentene-based polymer (A) obtained by graft-modifying an ethylenic unsaturated monomer satisfying the following requirements (I) to (III). (I) The amount of a structural unit derived from an ethylenic unsaturated monomer is in the range of 0.9 to 5.0 mass%. (II) The intrinsic viscosity [η] measured at 135°C in a decalin solvent is in the range of 0.5 to 5.0 dl/g. (III) The melting point (Tm) measured by a differential scanning calorimeter (DSC) is in the range of 200 to 245°C.SELECTED DRAWING: None 【課題】本発明の目的は、基材フィルムに塗工し、延伸した際に、割れやクラックが発生せず、塗膜強度に優れるコーティング剤を得ること、さらには、基材フィルム層とコーティング剤とを含む層とを含む積層体を得ることにある。【解決手段】本発明は、下記要件（Ｉ）～（III）を満たすエチレン性不飽和単量体によってグラフト変性されてなる４－メチル－１－ペンテン系重合体（Ａ）を含むコーティング剤に係る。（Ｉ）エチレン性不飽和単量体に由来する構造単位の量が、０．９～５．０質量％の範囲にある。（II）デカリン溶媒中、１３５℃で測定される極限粘度［η］が、０．５～５．０ｄｌ／ｇの範囲にある。（III）示差走査熱量計（ＤＳＣ）で測定した融点（Ｔｍ）が、２００～２４５℃の範囲にある。【選択図】なし
