Title: (METH)ACRYLIC MODIFIED SILOXANE COMPOUND
Abstract:
[Problem] To provide an additive which has a reactive group having excellent active energy ray curability and which, without bleeding over time when added to paint, imparts excellent leveling and anti-foaming properties to paint. [Solution] This (meth)acrylic modified siloxane compound, represented by expression (a1), has, optionally on the terminal, as a branched-chain of a linear polysiloxane skeleton, a specific number of groups having a (meth)acryloyl group at the terminal and having a (poly)oxyalkylene skeleton represented by -(CaH2aO)b-; this paint additive comprises the (meth)acrylic modified siloxane compound.
