- a cationically curable silicone resin;
- an epoxy resin;
- and
- an acrylic resin,
- wherein the acrylic resin is constituted by an acrylic monomer having an oxygen equivalent of 100 or more.
2 more elements
A water-repellent resin comprising:
- a resin composition containing:
- a cationically curable silicone resin,
- an epoxy resin, and
- an acrylic resin,
- wherein the acrylic resin is constituted by an acrylic monomer having an oxygen equivalent of 100 or more.
2 more elements
A liquid ejecting head comprising:
- a member having an ejection port;
- and
- a resin composition that contains a cationically curable silicone resin, an epoxy resin, and an acrylic resin constituted by an acrylic monomer having an oxygen equivalent of 100 or more, and that is disposed on at least a surface of the member in a periphery of the ejection port by patterning.
A method for producing a resin composition that contains a cationically curable silicone resin, an epoxy resin, and an acrylic resin constituted by an acrylic monomer having an oxygen equivalent of 100 or more, the method comprising:
- causing a mixture containing a silicone monomer, an epoxy monomer, and an acrylic monomer having an oxygen equivalent of 100 or more to react by using a cationic polymerization initiator.
