Abstract: An object of the present invention is to provide a shape supporting support material which can be efficiently removed after molding in addition manufacturing and an active energy ray-curable resin composition used for forming the support material. An active energy ray-curable resin composition containing the ionic monomer (A), the nonionic water-soluble monomer (B), the nonpolymerizable compound (C), and the photopolymerization initiator (D), and/or the polyfunctional monomer (E) is used. The support material can be thereby efficiently removed from the formed roughly modeled product. Furthermore, a three-dimensional modeled product having a non-contaminated surface and high molding accuracy can be obtained.

Abstract: Coating compositions including 0.5 to 30.0% by mass of acrylic polymers (A) and 70.0 to 99.5% by mass of polymerizable compounds (B) are provided. The acrylic polymers (A) contain a branched alkyl group having 3 to 20 carbon atoms and/or a branched or unbranched alkenyl group having 3 to 20 carbon atoms in the side chain. The coating compositions can form non-adhesive coating layers with good adhesion to various resinous base materials excellent surface hardness, tack resistance, bending resistance, scratch resistance, shrinkage resistance and moisture heat resistance. The coating compositions also can form adhesive coating layers with excellent close adhesion, adhesiveness, transparency, contamination resistance, heat and moisture resistance, yellowing resistance, and step followability. Moreover, various laminates, cover films, cover substrates and the like having these coating layers on one side or both sides of the resin films and/or resinous base materials are provided.

Abstract: A method for manufacturing a three-dimensional molded product capable of performing support at high accuracy using a support material having sufficient hardness and rigidity, capable of removing the support material efficiently after molding, and requiring no finishing step in manufacturing a three-dimensional molded product by an inkjet optical molding method, and a three-dimensional molded product manufactured by this method. A roughly molded product formed from a model material forming a molded product and a support material supporting the shape of the model material during molding is immersed in a washing liquid. The support material swells at a swelling ratio of 10% or more, and is thereby peeled from an interface with the model material having a swelling ratio of 1% or less. Then, the support material is easily and completely removed without applying an external force. Furthermore, a three-dimensional molded product can be manufactured with high accuracy and high efficiency.
