A spray foam formulation used to form a spray foam insulation layer in a wall structure is described. The formulation may include the reaction product of a polyisocyanate compound and a polyol compound; a fire retardant chosen from at least one of a non-halogenated fire retardant; and a reactive halogen-containing fire retardant, and a carbohydrate. The spray foam insulation layer has an insulative R value of 3.0 to 7.2 per inch, and a density of between about 0.3 to about 4.5 pcf. Further, spray foam insulation made from the spray foam formulation may have fire retardant characteristics that are equivalent to or better than a similar spray insulation foam insulation using non-reactive halogenated fire retardants such as tris(1-chloro-2-propyl)phosphate (TCPP).

It has been conventionally difficult to achieve both storage stability and photocurability by addition of a polythiol compound to a compound having a (meth)acryloyl group. A photocurable composition contains components (A) to (D): Component (A): a compound having a (meth)acryloyl group, Component (B): a polythiol compound, Component (C): a photoinitiator, Component (D): a storage stabilizer having pKa of 1.0 to 4.0 (containing no component (A)).

Provided are a composite photosensitive element and a method for preparing a composite photosensitive element, and the composite photosensitive element includes a photosensitive element and a near-infrared absorption layer pasted on the photosensitive element, wherein the near-infrared absorption layer includes a copper complex, and the copper complex is formed from a copper compound providing copper ions, phosphoric acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein, wherein the OD value of the near-infrared absorption layer for the incident light wavelength from 930-950 nm is greater than 4. The present disclosure forms a filtering film directly on the photosensitive element instead of using a traditional filter assembly to reduce the size of the assembled product. The filtering film can be further processed and shaped to have functions of micro-lens.

The present invention relates to the use of NOR-HALS compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters and duro-plastic polymers, such as polyepoxides.
