Abstract
Provided is a member in which the strength of a second layer located on the outermost surface of the exterior is improved in order to sufficiently exhibit and maintain the functions, to thereby improve impact resistance and scratch resistance. The member is a member including a base material, a first layer, a second layer, and a third layer in the stated order, wherein the first layer is an inorganic porous layer in which a plurality of inorganic particles are joined to each other, and the first layer and the second layer have a total thickness of 0.3 μm or more and 2 μm or less, wherein the third layer contains a resin and has a thickness of 0.4 μm or more and 2,000 μm or less, and wherein the second layer contains the inorganic particles and the resin.
Claims19
A member comprising a base material, a first layer, a second layer, and a third layer in the stated order,
- wherein the first layer is an inorganic porous layer in which a plurality of inorganic particles are joined to each other,
- wherein the third layer is a layer containing a resin,
- wherein the second layer is a layer containing the plurality of inorganic particles and the resin,
- wherein the first layer and the second layer have a total thickness of 0.3 μm or more and 2 μm or less, and
- wherein the third layer has a thickness of 0.4 μm or more and 2,000 μm or less.
A method of producing a member comprising:
- applying a coating liquid containing a plurality of inorganic particles and a solvent onto a base material to form a coating film;
- drying and/or calcining the base material having the coating film formed thereon to form a porous layer in which the plurality of inorganic particles are joined to each other;
- and
- applying a coating liquid containing a resin onto the porous layer to cause part of the resin to intrude into part of the porous layer, followed by curing,
- wherein the member has a region of the porous layer, into which the resin is prevented from intruding, having a thickness of 0.3 μm or more and 2 μm or less and a region, in which the resin is cured without intruding into the porous layer, having a thickness of 0.4 μm or more and 2,000 μm or less.
