Provided are: a phosphate amine salt composition which can be used as a flame retardant that is capable of imparting excellent flame retardancy and weather resistance to synthetic resins without a risk of corroding a processing machine; a phosphate amine salt flame retardant composition; a flame-retardant synthetic resin composition containing the same; and a molded article thereof. The phosphate amine salt composition contains at least one phosphate amine salt, and the ammonium cation content therein is 100 to 2,000 ppm by mass. An amine in the phosphate amine salt composition is preferably melamine or piperazine.

Phosphate amine salt composition, phosphate amine salt flame retardant composition, flame retardant synthetic resin composition containing same, and molded article of flame retardant synthetic resin composition

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

A flame retardant composition according to the present invention is a phosphate-based flame retardant including a (poly)phosphate, in which F and N satisfy 8.0&#xd7;10&#x2264;F/N&#x2264;20.0 and F&#x2264;21.0, assuming that F (ppm) is a content of elemental iron and N (ppm) is a content of elemental sodium in the flame retardant composition as measured in accordance with the following procedure.

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 process for producing a pyrophosphate, particularly melamine pyrophosphate useful as a flame retardant, efficiently in high yield is provided. The process includes firing an orthophosphate, preferably melamine orthophosphate, in the presence of a silicone oil, preferably methylphenyl silicone oil preferably at 120&#xb0; to 350&#xb0; C. Examples of useful firing equipment include a hot air dryer, a kneader, a Henschel mixture, a fluidized bed dryer, a rotary kiln, a paddle dryer, an extruder, a vibrating dryer, a far-infrared conveyor furnace, and a microwave firing furnace.
