Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A solventless UV curable mixture having an acute oral toxicity value (LD 50 ) of 5 grams/kilogram or greater comprising, (a) an oxirane containing organic or silicone resin and (b) an effective amount of a diaryliodonium hexafluorometalloid salt selected from the class consisting of phosphates, arsenates and antimonates having at least one nuclear bound --OR radical attached to an aryl radical of the disryliodonium hexafluorometalloid salt, where R is an alkyl radical having from 8-20 carbon atoms.
Claim 2
Dependent Claim
77 words
A solventless UV curable mixture having an acute oral toxicity value (LD 50 ) of 5 grams/kilogram or greater comprising, (a) an oxirane containing organic or silicone resin and (b) an effective amount of a diaryliodonium hexafluorometalloid salt selected from the class consisting of phosphates, arsenates and antimonates having at least one nuclear bound --OR radical attached to an aryl radical of the disryliodonium hexafluorometalloid salt, where R is an alkyl radical having from 8-20 carbon atoms.
Claim 3
Dependent Claim
19 words
A UV curable mixture in accordance with claim 1 where the diaryliodonium hexafluorometalloid salt is a diaryliodonium hexafluoroantimonate salt.
Claim 4
Dependent Claim
29 words
A UV curable mixture in accordance with claim 2, where R is octyl in the nuclear bound --OR radical attached to the aryl radical of the diaryliodonium hexafluroometalloid salt.
