Benefits of technology

Another object of the present is to provide a photopolymerizable composition excellent in the storage stability.

Problems solved by technology

However, these photopolymerization initiators are extremely low in the photopolymerization initiation ability to visible light of 400 nm or more as compared with the photopolymerization initiation ability to ultraviolet light of 400 nm or less and accordingly, thus they are remarkably limited in their application range.
These conventional techniques are surely effective to visible light rays, however, they are bound to problems such that the sensitivity is insufficient or even if high sensitivity is achieved, the storage stability is poor and hence, these systems cannot be used in practice.

Abstract

A photopolymerizable composition is disclosed, which comprises an addition-polymerizable compound having at least one ethylenically unsaturated double bond, a sensitizing dye represented by the following formula (I):wherein the all symbols are defined in the disclosure, and a titanocene compound.

Description

FIELD OF THE INVENTIONThe present invention relates to a photopolymerizable composition, more particularly, it relates to a photopolymerizable composition highly sensitive to light rays in the visible light region and capable of showing good sensitivity also to Ar.sup.+ laser, YAG-SHG laser or the like light source.BACKGROUND OF THE INVENTIONA large number of image formation methods using a photopolymerization system have been conventionally known and used over a wide range of fields such as printing plate, printed circuit, paint, ink, hologram recording and three-dimensional formation. For example, there are known a method where a photopolymerizable composition comprising an addition-polymerizable compound having an ethylenic double bond and a photopolymerization initiator, further, if desired, an organic high molecular binder and a thermal polymerization inhibitor is provided on a support to form a film layer, the layer is imagewise exposed to a desired image to cure the exposed a...
