Abstract

Provided are an active energy ray-curable composition fox flooring materials, which is unlikely to cause a curing defect between a cured portion and an uncured portion even when a movable curing device having a light source is used is unlikely to cause yellowing attributable to exposure to natural light for a long period of time, and exhibits a high re-coatability, while exhibiting conventional physical performance, and a construction method therefor. Further, also provided are an active energy ray-curable composition for antibacterial flooring materials, which has antibacterial properties, and a construction method therefor. The active energy ray-curable composition for flooring materials is formed by appropriately applying a specific carboxyl group-containing active energy ray-polymerizable compound, a specific urethane oligomer, a specific hyperbranched oligomer, specific polyfunctional acrylate, and a specific photopolymerization initiator in combination.

First claim

1 . An active energy ray-curable composition for flooring materials, which comprises an active energy ray-polymerizable compound and a photopolymerization initiator,
wherein the active energy ray-polymerizable compound includes the following materials (a), (b), (c), and (d):
(a) a carboxyl group-containing active energy ray-polymerizable compound represented by Formula (1);

wherein R1 represents a hydrogen atom or a methyl group, and X represents an organic group:
(b) a urethane oligomer;
(c) a hyperbranched oligomer; and
(d) polyfunctional acrylate.

2 . The active energy ray-curable composition for flooring materials according to claim 1 , wherein the photopolymerization initiator is methyl benzoyl formate.

3 . The active energy ray-curable composition for flooring materials according to claim 1 , which further comprises (e) an antibacterial agent.

4 . The active energy ray-curable composition for flooring materials according to claim 1 , wherein the (e) antibacterial agent is a silver-based antibacterial agent.

5 . The active energy ray-curable composition for flooring materials according to claim 1 , which further comprises (f) an acrylic leveling agent.

6 . An construction method, which comprises:
curing the active energy ray-curable composition for flooring materials according to claim 1 using a movable active energy ray irradiation device.

7 . Flooring materials which are obtained by the construction method according to claim 6 .

8 . A floor for which the flooring materials according to claim 7 are used.
