Resin composition
A resin composition including: at least one resin ingredient selected from the group made of a resin (A) having a side chain (a) containing a hydrogen-bonding cross-linking moiety with a carbonyl-containing group and/or a nitrogen-containing heterocycle and having a glass transition point of 25° C. or lower, and a resin (B) containing a hydrogen-bonding cross-linking moiety and a covalent-bonding cross-linking moiety in a side chain and having a glass transition point of 25° C. or lower, wherein both the resin (A) and the resin (B) are a reaction product of a cross-linking agent with a maleic anhydride-modified thermoplastic resin having a melting point of 68° C. to 134° C. and a maleation rate of 0.5 to 2.5% by mass.
1. A resin composition comprising:
at least one resin ingredient selected from the group consisting of a resin (A) having a side chain (a) containing a hydrogen-bonding cross-linking moiety with a carbonyl-containing group and/or a nitrogen-containing heterocycle and having a glass transition point of 25° C. or lower, and a resin (B) containing a hydrogen-bonding cross-linking moiety and a covalent-bonding cross-linking moiety in a side chain and having a glass transition point of 25° C. or lower, wherein
both the resin (A) and the resin (B) are a reaction product of a cross-linking agent with a maleic anhydride-modified thermoplastic resin having a melting point of 68° C. to 134° C. and a maleation rate of 0.5 to 2.5% by mass.
2. The resin composition according to claim 1 , wherein the cross-linking agent is a compound having at least one of a hydroxyl group, an amino group, an imino group, and a thiol group.
3. The resin composition according to claim 1 , wherein the maleic anhydride-modified thermoplastic resin is a polyolefin-based resin modified with maleic anhydride.
4. The resin composition according to claim 3 , wherein the polyolefin-based resin modified with maleic anhydride is a high density polyethylene modified with maleic anhydride.
