Photopolymerizable composition and recording material using same

A recording material comprising a support, and a light and heat sensitive recording layer containing a color-developing component encapsulated in heat-responsive microcapsules and a photopolymerizable composition on the exterior of the heat-responsive microcapsules, wherein said photopolymerizable composition comprises a substantially colorless polymerizable compound having an ethylenic unsaturated group and a moiety that reacts with the color-developing component to form a color, an organic borate represented by the following formula (1) and having a melting point of no more than 100° C., and a cationic compound that interacts with the organic borate:

• 30
• wherein R1 represents an alkyl group, R2 represents an electron-donating group, R3 to R6 each represent a hydrogen atom or a substituent, the sum of Hammett's substituent constants σ of R2 to R6 is 0 to 1, and Z+ represents a group that can form a cation.
