The present invention relates to a method for producing a semi-IPN-type composite, which is characterized in that a polyurethane (A), a hydrophilic acrylic monomer (b1) and an acrylic monomer (b2) having a hydrolyzable silyl group are mixed together. The polymer (B) is mixed to cross-link the polymer (B). The hydrophilic acrylic monomer (b1) preferably contains an acrylic monomer (b1-1) having an amide group and an acrylic monomer (b1-2) having an oxyethylene group. In addition, the acrylic monomer (b1-1) having an amide group, the acrylic monomer (b1-2) having an oxyethylene group, and the acrylic monomer (b2) having a hydrolyzable silyl group are The polymerization ratio (molar ratio) is in the range of (b1-1)/(b1-2)/(b2)=50/49.5/0.5 to 89/1/10. |
