FIELD: medicine.

SUBSTANCE: group of inventions relates to a kit for producing a photocurable composition and a kit for producing a material for repairing dentures, which includes such a photocurable composition. Each of said kits contains: per 100 weight fractions of component (a), including a polymerized monomer, from 150 to 210 weight fractions of component (b), comprising resin particles having a weight-average molecular weight of 30,000 to 2,000,000, determined by gel permeation chromatography, from 0.15 to 0.8 weight fractions of component (c), including α-diketone compound, from 0.25 to 1.0 weight fractions of component (d), including a tertiary amine compound, and from 0.008 to 0.08 weight fractions of component (e), including α-hydroxycarboxylic acid, having an acid dissociation constant in water of 3.0 or more (at 25 °C) and two or more carbonyl groups in one molecule. Kit contains a liquid material which contains component (a), component (d) and component (e); and powder material, which contains component (b) and component (c).

EFFECT: use of the declared group of inventions reduces the amount of surface-unpolymerized products in the cured material and achieving greater depth of photocuring in the photocurable composition used in the photocurable type material for repairing dentures and the like.
