Abstract

A liquid composition that contains a polymerizable compound and a solvent, and that can form a porous resin. The liquid composition, when stirred, transmits at least 30 percent of incident light having a wavelength of 550 nm. The haze value of an containing the liquid composition increases by 1.0 percent or more when the element containing the liquid composition is cured.

First claim

wherein, when an element comprising the liquid composition is cured, a haze value of the element increases by 1.0 percent or more, and
wherein the porous resin has a pore size of from 0.01 to 10 μm.

2. The liquid composition according to claim 1 ,
wherein a relative energy difference (RED) 1 , based on a Hansen solubility parameter (HSP) A of a resin formed by polymerizing the polymerizable compound, an interaction diameter B of the resin, and an HSP of the solvent, is 1.00 or greater,
wherein RED 1={Distance between (the HSP A of the resin) and (the HSP of the solvent)}/(the interaction diameter B of the resin).

3. The liquid composition according to claim 1 ,
wherein a relative energy difference (RED) 2, based on a Hansen solubility parameter (HSP) C of the polymerizable compound, an interaction diameter D of the polymerizable compound, and an HSP of the solvent, is 1.05 or less,
wherein RED 2={Distance between (the HSP C of the polymerizable compound) and (the HSP of the solvent)}/(the interaction diameter D of the polymerizable compound).

4. The liquid composition according to claim 1 , which comprises:
from 10.0 to 50.0 percent by mass of the polymerizable compound, and
from 50.0 to 90.0 percent by mass of the solvent.

5. The liquid composition according to claim 1 , which has a viscosity of from 1 to 150 mPa·s at 25 degrees C.

6. The liquid composition according to claim 1 , which has a viscosity of from 1 to 30 mPa·s at 25 degrees C.
