Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
63 words
A laminate suitable for use as a graphic arts board comprising two solid ABS resin sheets, said ABS resin comprising a pigment and UV stabilizer, said solid sheets being fusion bonded to the upper and lower surfaces of a foam resin core containing a blend of polystyrene and ABS resin, a nucleating agent, and an antistatic agent on the surfaces of the laminate.
Claim 2
Dependent Claim
63 words
A laminate suitable for use as a graphic arts board comprising two solid ABS resin sheets, said ABS resin comprising a pigment and UV stabilizer, said solid sheets being fusion bonded to the upper and lower surfaces of a foam resin core containing a blend of polystyrene and ABS resin, a nucleating agent, and an antistatic agent on the surfaces of the laminate.
Claim 3
Dependent Claim
54 words
The laminate of claim 1 wherein said antistatic agent is a mixture of n-alkyl (60 percent C 14 , 30 percent C 16 , 5 percent C 12 , 5 percent C 18 ) dimethyl benzyl ammonium chlorides and n-alkyl (68 percent C 12 , 32 percent C 14 ) dimethyl ethylbenzyl ammonium chlorides.
Claim 4
Dependent Claim
