Abstract
In a photocurable resin composition containing a polyfunctional radically polymerizable compound (A), a monofunctional radically polymerizable compound (B), and a curing agent (D), the polyfunctional radically polymerizable compound (A) has an ethylenically unsaturated group equivalent of 700 g/eq or more and 7,000 g/eq or less, and fluororesin particles (C) are added in an amount of 5 parts or more by mass and 30 parts or less by mass based on a total of 100 parts by mass of the polyfunctional radically polymerizable compound (A) and the monofunctional radically polymerizable compound (B).
Claims17
A photocurable resin composition, comprising:
- a polyfunctional radically polymerizable compound (A);
- a monofunctional radically polymerizable compound (B);
- particles that are the only particles in the photocurable resin composition;
- and
- a curing agent (D),
- wherein the polyfunctional radically polymerizable compound (A) has an ethylenically unsaturated group equivalent of 700 g/eq or more and 7,000 g/eq or less,
- the polyfunctional radically polymerizable compound (A) is contained in an amount of 20 parts or more by mass and 75 parts or less by mass based on a total of 100 parts by mass of the polyfunctional radically polymerizable compound (A) and the monofunctional radically polymerizable compound (B),
- the particles are fluororesin particles (C) each of which contains a fluororesin in whole or in part thereof,
- the fluororesin particles (C) are contained in an amount of 5 parts or more by mass and 30 parts or less by mass based on the total of 100 parts by mass of the polyfunctional radically polymerizable compound (A) and the monofunctional radically polymerizable compound (B), and
- the fluororesin particles (C) have an average particle size of 0.5 or more and 50 μm or less.
