Claims
- 1. An improved liquid marking composition, wherein the improvement comprises incorporating into said composition voided latex particles formed from a multistaged polymer particle having a core polymer polymerized from ethylenically unsaturated monomers and having a shell polymerized from at least about 25% by weight, based on the weight of the shell, of an ethylenically unsaturated crosslinking comonomer.
- 2. An improved liquid marking composition, wherein the improvement comprises incorporating into said composition voided latex particles formed from a multistaged polymer particle having a core polymer polymerized from ethylenically unsaturated monomers and having an outermost shell formed from methyl methacrylate and from at least about 5% by weight, based on the weight of the shell of an ethylenically unsaturated crosslinking comonomer.
- 3. The composition of claims 1 or 2 wherein said crosslinking comonomer is a comonomer selected from the group consisting of alkylene glycol diacrylates, alkylene glycol dimethacrylates, 1,3-glycerol dimethacrylate, 1,1,1-trimethylolpropane dimethacrylate, 1,1,1-trimethylolethane diacrylate, pentaerythritol trimethacrylate, 1,2,6-hexane triacrylate, sorbitol pentamethacrylate, methylene bisacrylamide, methylene bis-methacrylamide, divinylbenzene, vinyl methacrylate, vinyl crotonate, vinyl acrylate, vinylacetylene, trivinyl-benzene, triallyl cyanurate, divinylacetylene, divinylethane, divinyl sulfide, divinyl ether, divinyl sulfone, diallyl cyanamide, ethylene glycol divinyl ether, diallyl phthalate, divinyldimethylsilane, glycerol trivinyl ether, divinyl adipate, dicyclopentenyl (meth)acrylates; dicyclopentenyloxy (meth)acrylates, unsaturated esters of glycol monodicyclopentenyl ethers, allyl esters of .alpha.,.beta.-unsaturated monocarboxylic acids having terminal ethylenic unsaturation and allyl esters of .alpha.,.beta.-unsaturated dicarboxylic acids having terminal ethylenic unsaturation.
- 4. The composition of claims 1 or 2 wherein said crosslinking comonomer is a comonomer selected from the group consisting of an allyl ester of .alpha.,.beta.-unsaturated monocarboxylic acid having terminal ethylenic unsaturation and .alpha.,.beta.-unsaturated dicarboxylic acid having terminal ethylenic unsaturation.
- 5. The composition of claims 1 or 2 wherein said crosslinking comonomer is allyl methacrylate.
