Abstract
Provided are a laminate including: a glass substrate; a layer (ca) including a binder; a particle (a2) having an average primary particle diameter of 100 nm to 380 nm; and a layer (b) including a pressure sensitive adhesive, in which the layer (ca) is present on a side closer to the glass substrate than the layer (b), and the particle (a2) is buried in layers obtained by combining the layer (ca) and the layer (b) and protrudes from an interface of the layer (ca) on a side opposite to an interface of the layer (ca) on the glass substrate side, an antireflection product using the laminate, and a method of manufacturing the laminate and an antireflection product.

A laminate comprising:
- a glass substrate;
- a layer (ca) including a binder;
- a particle (a2) having an average primary particle diameter of 100 nm to 380 nm;
- and
- a layer (b) including a pressure sensitive adhesive,
- wherein the layer (ca) is present on a side closer to the glass substrate than the layer (b), and
- the particle (a2) is buried in layers obtained by combining the layer (ca) and the layer (b) and protrudes from an interface of the layer (ca) on a side opposite to an interface of the layer (ca) on the glass substrate side.
A method of manufacturing a laminate comprising, in order:
- a step (1) of providing a binder compound and a particle (a2) having an average primary particle diameter of 100 nm to 380 nm on a glass substrate, in a thickness in which the particle (a2) is buried in a layer (a) including the binder compound;
- a step (2) 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 (a);
- a step (3) of causing a position of an interface between the layer (a) and the layer (b) to come close to the glass substrate side such that the particle (a2) is buried in layers obtained by combining the layer (a) and the layer (b) and protrudes from an interface of the layer (a) on a side opposite to an interface of the layer (a) on the glass substrate side;
- and
- a step (4) of curing the layer (a) in a state in which the particle (a2) is buried in the layers obtained by combining the layer (a) and the layer (b).
