<p>PROBLEM TO BE SOLVED: To provide a coating agent which meets requirements of baking sealing properties at low temperatures and high adhesion strength.SOLUTION: A coating agent contains a modified 1-butene-based copolymer obtained by graft-modifying 100 pts. mass of a 1-butene-α-olefin copolymer (Y) having (i) a ratio (Mw/Mn) of the wt. average molecular wt. Mw to the number average molecular wt. Mn of 1.0-3.5, measured by GPC, and (ii) a crystal fusion heat of 20-70 J/g with 0.1-15 pts. mass of a polar monomer.</p> |
