摘要： A radiation curable resin composition for a Fresnel lens is provided, which exhibits a high elastic modulus and a high refractive index and is superior in adhesion to the plastic substrate and is superior in transparency. A lens layer exhibits excellent shape retention over a wide temperature range and is less likely to chip and crack due to an external force. A Fresnel lens sheet using the radiation curable resin composition is also provided. The resin composition comprises, as an essential component, an epoxy (meth)acrylate (a) having an epoxy equivalent per weight of 450 g/eq or more, which has a cyclic structure and two or more (meth)acryloyl groups; a specific trifunctional (meth)acrylate (b); a (meth)acrylate (c) having a molecular weight of 700 or less from an aliphatic polyhydric alcohol having an oxypropylene structure; and a monofunctional (meth)acrylate (d) having a cyclic structure.

摘要： An object of the present invention is to provide the resin composition for electro-photographic toner, which the electro-photographic toner to be obtained by it is superior to low temperature fixing properties and a hot offset resistance, and the electro-photographic toner thereof. To be achieved this purpose, multi-branched state polyester structure having a structure representing the following structural formula (1) as a repeating unit, is made into a main skeleton (In the formula, R expresses an aliphatic hydrocarbon group, and n shows the number of repeating units of a branched structure and is an average of 1-5.) *a is a node of the carbon atom of a carbonyl group, *b is a node of an oxygen atom, and *b is bonded to *a in the other repeating unit of the structural formula (1)). In addition, polyester resin (A) having a ratio of 25 to 95% of the weight for alkyl group of the number of carbon atoms 20-80 or alkenyl group of the number of carbon atoms 20-80 to the molecular terminal and aliphatic series crystalline polyester resin (B) is contained. The electro-photographic toner containing the resin composition for electro-photographic toner and this composition is provided.
