Abstract
A free radical curable liquid having a specific weight after curing measured at 25° C. of less than 1.00 g/cm3 including: a) one or more photoinitiators; b) one or more free radical polymerizable monomers or oligomers; and c) hollow particles and/or a free radical crosslinkable polymer selected from the group consisting of polyethylene, polypropylene, polybutadiene, polymethylpentene, poly(ethylene-vinylacetate), poly(ethylene-ethyl acrylate) and poly(styrene-butadiene) and copolymers thereof; wherein at least the free radical crosslinkable polymer or at least one of the one or more free radical polymerizable monomers or oligomers includes one or more hydrolyzable groups which upon hydrolyzation form an acid group or salt thereof; and wherein the free radical curable liquid contains no more than 10 wt % of organic solvent.
