Abstract
A laminate includes a support, a layer (b) including a pressure sensitive adhesive, particles (a2) having an average primary particle diameter of 100 nm to 380 nm, and a layer (ca) including a resin, in which the layer (b) is provided closer to the support than the layer (ca), the particles (a2) are buried in a layer obtained by combining the layer (b) and the layer (ca) and protrudes from an interface of the layer (ca) on the support side, and a portion including the particles (a2) and the layer (ca) is peelable from the layer (b).
Claims5
A method of manufacturing a laminate, comprising, in this order:
- a step (1) of providing particles (a2) having an average primary particle diameter of 100 nm to 380 nm and a curable compound (a1) on a temporary support in a thickness in which the particles (a2) are buried in a layer (a) including the curable compound (a1);
- a step (2) of curing a portion of the layer (a) to obtain a layer (ca);
- a step (3) of bonding a layer (b) of a pressure sensitive film having a support and the layer (b) including a pressure sensitive adhesive on the support, to the layer (ca);
- a step (4) of causing a position of an interface of the layer (ca) on a side of the support to come close to a side of the temporary support such that the particles (a2) are buried in a layer obtained by combining the layer (ca) and the layer (b) and protrude from the interface of the layer (ca) on the side of the support;
- and
- a step (5) of peeling the temporary support.
