A particulate ultraviolet absorber is provided and includes a predetermined triazine-based compound, in which in a case where a loose bulk density is denoted by D1 and a tight bulk density is denoted by D2, which are measured under predetermined measurement condition, compressibility represented by [(D2&#x2212;D1)/D2]&#xd7;100 is 5.0% or more and 40% or less.

Particulate ultraviolet absorber and resin composition

Disclosed is an insect-proofing film and an insect-proofing cover capable of preventing flying insects from being attracted to or flying toward light-emitting elements, indoor space, and crops, and more specifically, provides an insect-proofing film and an insect-proofing cover wherein the insect-proofing film/insect-proofing cover includes at least one type of triazine-based compound represented by formula (1). (In formula (1), Rto Reach represent a Clinear or branched alkyl group, etc.; and Rto Reach represent a Calkyl group, a Calkenyl group, etc.) 

Insect-proofing film and insect-proofing cover

A photocurable composition contains at least one ultraviolet absorber represented by Formula (1), and a hard coating agent including the photocurable composition. wherein R, Rand Rmay be the same as or different from each other and represent a branched or linear alkyl group with 1-20 carbon atoms and is substituted with a (meth)acryloyloxy group; the alkyl group may be substituted with a hydroxyl group, an alkoxy group having 1-8 carbon atoms, or an acyloxy group having 1-8 carbon atoms; the alkyl group may be interrupted by an oxygen atom, a sulfur atom, a carbonyl group, an ester group, an amide group, or an imide group; and R, Rand Rmay be the same as or different from each other and represent a hydrogen atom, a halogen atom, a hydroxyl group, an alkyl group having 1-12 carbon atoms, or an alkoxy group having 1-12 carbon atoms.

Photocurable composition and hard coating agent

A novel compound excellent in heat resistance, resistance to volatilization, and compatibility with a resin component and useful as a UV absorber and a synthetic resin composition containing the compound are provided. Specifically provided are a triazine compound of general formula (1), preferably general formula (2) and a synthetic resin composition containing 0.001 to 20 parts by mass of the compound per 100 parts by mass of a synthetic resin. The details of formulae (1) and (2) are as defined in the description. 

Triazine compound and synthetic resin composition using same

A stabilizer for chlorine-containing resins of the invention consists of a polyol mixture composed of pentaerythritol and condensates thereof, wherein, with respect to the total amount of the polyol mixture, the content of pentaerythritol having a degree of condensation (n) of 1 is 0 to 10% by mass and the total content of pentaerythritol and condensates thereof having a degree of condensation (n) of 1 to 3 is 5 to 30% by mass. A chlorine-containing resin composition of the invention contains, with respect to 100 parts by mass of a chlorine-containing resin, 0.01 to 10 parts by mass of the above-mentioned stabilizer for chlorine-containing resins.
