Composition for laminated material used for medical lubricating member, laminated material used for medical lubricating member, medical lubricating member, medical device, and method for producing laminated material used for medical lubricating member

A medical lubricating member comprising:

• a laminated material used for a medical lubricating member, the laminated material comprising:
• a substrate a;
• and
• a layer b disposed on the substrate a,
• wherein the layer b includes a catalyst for crosslinking reaction and a crosslinked polymer including, as a constituent component, a polymer b including a polysiloxane structure,
• the polymer b includes, as a constituent component, at least one of an acrylic acid component, an acrylic acid ester component, an acrylamide component, or a styrene component,
• the polymer b has at least one of a hydroxy group, a carboxy group, an amino group, an isocyanate group, an oxazolinyl group, an epoxy group, a vinyl group, an ethynyl group, a sulfanyl group, an azide group, a trialkoxysilyl group, or an acid anhydride structure, and
• the crosslinked polymer has a crosslinking agent component including at least one of a crosslinking agent having a structural unit represented by formula (CL1) below or a crosslinking agent represented by formula (CL2) below,
• wherein RCL represents a hydrogen atom or an organic group,
• X represents a hydroxy group, a carboxy group, an amino group, an isocyanate group, an oxazolinyl group, an epoxy group, a vinyl group, an ethynyl group, a sulfanyl group, an azide group, a trialkoxysilyl group, or a group having an acid anhydride structure,
• Y represents an m-valent linking group,
• m represents an integer of 2 or more,
• Rdm has the same definition as X;
• and
• a layer c that is disposed on the layer b constituting the laminated material and that includes a hydrophilic polymer.
