Photopolymerizable composition with epoxy stabilizers

DETAILED DESCRIPTION OF THE INVENTION A detailed explanation is given below as to the main components used in the present invention.
First of all, suitable epoxy compounds which can be used as component (d) include those which are extensively used as stabilizers or plasticizers for polyvinyl chloride.
Suitable examples include epoxidized aliphatic monoesters such as, for example, the epoxidized derivatives of alkyl oleates (e.
g.
, methyl oleate, butyl oleate, octyl oleate, etc.
) having the formula: ##STR3## wherein R.
sup.
11 is an alkyl group having up to 10 carbon atoms, which can be obtained from soybean oil or beef tallow (commercially available products include Epocizer, produced by Dai-Nippon Ink Chem.
Ind.
); and the polyglycidyl ethers of polyhydric alcohols (e.
g.
, trimethylolpropane, pentaerythritol, sorbitol, glycerol, triethylene glycol, polyethylene glycol, etc.
) having the formula: ##STR4## wherein p is an integer of 2 to 6, and R.
sup.
12 is a divalent to hexavalent residue of a polyol (commercially available products include Epiol G-100, produced by Nippon Oils & Fats Co.
).
Further, epoxidized triglycerides having the formula: ##STR5## wherein R.
sup.
13, R.
sup.
14 and R.
sup.
15, which may be the same or different, are each an epoxidized alkyl group having 2 to 10 carbon atoms, e.
g.
, epoxidized soybean oil (commercially available products include Newcizer 510, produced by Nippon Oils & Fats Co.
, etc.
); alkyl glycidyl ethers having the formula: ##STR6## wherein R.
sup.
16 is an alkyl group having 1 to 10 carbon atoms, e.
g.
, methyl glycidyl ether, ethyl glycidyl ether, etc.
; alkenyl glycidyl ethers having the formula: ##STR7## wherein R.
sup.
17 is an alkenyl group having 2 to 10 carbon atoms and also containing therein one double bond, e.
g.
, ally glycidyl ether; aryl glycidyl ethers having the formula: ##STR8## wherein O is a phenyl group or an alkylphenyl group, e.
g.
, phenyl glycidyl ether (commercially available under the trade name Epikote, products of Shell Chem.
Co.
); the epoxidized derivatives of alicyclic compounds having the formula: ##STR9## wherein R
