Thermal- and UV-curing adhesive composition

A thermal- and UV-curing adhesive composition used in assembling a camera module, the thermal- and UV-curing adhesive composition comprising

• (a) at least one urethane acrylate oligomer comprising at least one polycarbonate-based urethane acrylate oligomer,
• (b) at least one acrylate monomer,
• (c) at least one particulate rubber,
• (d) at least one polyamine curing agent having a primary amine and/or a secondary amine, and
• (e) at least one photopolymerization initiator,
• wherein the at least one urethane acrylate oligomer (a) has a weight average molecular weight of 4,000 or more, and
• the at least one particulate rubber (c) is present in an amount of 5% by weight or more in the entire composition.

A method of adhering a lens holder for a camera module to a camera module substrate having an image sensor fixed thereon,

• the method comprising adhering the lens holder to the substrate by using a thermal- and UV-curing adhesive composition, wherein the thermal- and UV-curing adhesive composition comprises
• (a) at least one urethane acrylate oligomer comprising at least one polycarbonate-based urethane acrylate oligomer,
• (b) at least one acrylate monomer,
• (c) at least one particulate rubber,
• (d) at least one polyamine curing agent having a primary amine and/or a secondary amine, and
• (e) at least one photopolymerization initiator,
• wherein the at least one urethane acrylate oligomer (a) has a weight average molecular weight of 4,000 or more, and
• the at least one particulate rubber (c) is present in an amount of 5% by weight or more in the entire composition.
