Title:
COATING AGENT FOR MODIFYING HEAT SEAL BASE MATERIAL, LAMINATE, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/045072
Kind Code:
A1
Abstract:
This coating agent for modifying a heat seal base material is coated onto a heat seal surface of a heat seal base material, the coating agent containing a block copolymer capable of forming a lamellar microphase-separated structure, and a liquid medium. The block copolymer has a block (A1) constituting a non-adsorption layer, and a block (B1) constituting a layer capable of adhering or fusing to the heat seal base material. The block (A1) is composed of nitrile-group-containing (meth)acrylic monomer units and alkyl-group-containing (meth)acrylic monomer units, and the proportion of the alkyl-group-containing (meth)acrylic monomer units per mol of the nitrile-group-containing (meth)acrylic monomer units is 0.1-0.8 mol (inclusive).
