The present application generally relates to EAA films including at least one triazine-based ultraviolet absorber. The present application also generally relates to retroreflective sheeting including an EAA film including a triazine-based ultraviolet absorber. One embodiments of the present application relates to a film, comprising poly(ethylene-co-acrylic acid) and a triazine-based UVA. Another embodiment of the present application relates to retroreflective sheeting, comprising: a plurality of cube corner elements; and a body layer adjacent to the cube corner elements, the body layer including poly(ethylene-co-acrylic acid) and a triazine-based UVA.

Films including triazine-based ultraviolet absorbers

The present application generally relates to EAA films including at least one triazine-based ultraviolet absorber. The present application also generally related to retroreflective sheeting including an EAA film including a triazine-based ultraviolet absorber. One embodiments of the present application relates to a film, comprising poly(ethylene-co-acrylic acid) and a triazine-based UVA. Another embodiment of the present application relates to retroreflective sheeting, comprising: a plurality of cube corner elements; and a body layer adjacent to the cube corner elements, the body layer including poly(ethylene-co-acrylic acid) and a triazine-based UVA.

Described are articles, laminates, sheets, coatings, retroreflective articles, pigments containing thioxanthone compounds that are fluorescent colorants.

Articles containing thioxanthone dyes

Oligomeric materials contain ultraviolet light absorbing compounds that are covalently bound to the oligomer backbone through an ester or amide linkage. These ultraviolet light absorbing oligomers may be combined with polymers such as polyolefins to provide protection against the harmful effects of ultraviolet light.

Polyolefin bound ultraviolet light absorbers

Daylight fluorescent articles are disclosed that utilize durable fluorescent pigment particles resulting from a fluorescent dye incorporated within a matrix polymer selected from polycarbonate, polyester and mixtures thereof and where the particles are of various desired shapes and sizes. Embodiments of such fluorescent pigment particles may also be retroreflective and are especially useful for pavement marking surfaces and retroreflective products for highway transportation safety.

Durable fluorescent organic pigments and methods of making

A fluorescent red article comprising a polymer matrix; and a perylene dicarboximide dye, wherein the article has chromaticity coordinates (x, y) within the area defined by (0.648, 0.351), (0.735, 0.265), (0.629, 0.281) and (0.565, 0.346) in terms of the CIE 1931 Standard Colorimetric System and measured using 0/45 geometry and evaluated with CIE Standard Illuminant D65 and a fluorescence luminance factor of at least about 8, and laminates, retroreflective materials, and methods of making thereof.

Fluorescent red article and retroreflective article made therefrom

An ultraviolet light absorbing material that resists blooming and migration is made up of a polyurethane or polyurea polymer and an amide functional ultraviolet light absorbing compound, wherein the polymer and the amide functional ultraviolet light absorbing compound are hydrogen bonded to one another. Polymeric films that contain a polymeric matrix and the ultraviolet light absorbing material are useful as the top layer in multilayer constructions such as retroreflective sheetings and conformable marking sheets.

Amide functional ultraviolet light absorbers for polyurethanes and polyureas

An ultraviolet light absorbing material that resists blooming and migration is made up of a fluoropolymer and an amide functional ultraviolet light absorbing compound, wherein the polymer and the amide functional ultraviolet light absorbing compound are hydrogen bonded to one another. Polymeric films that contain a polymeric matrix and the ultraviolet light absorbing material are useful as the top layer in multilayer constructions such as retroreflective sheetings and conformable marking sheets.

Amide functional ultraviolet light absorbers for fluoropolymers

An ultraviolet light absorbing material that resists blooming and migration is made up of a carboxyl functional polymer and an amide functional ultraviolet light absorbing compound, wherein the carboxyl functional polymer and the amide functional ultraviolet light absorbing compound are hydrogen bonded to one another. Polymeric films that contain a polyolefin and the ultraviolet light absorbing material are useful as the top layer in multilayer constructions such as retroreflective sheetings and conformable marking sheets.

UV light absorbing material comprising a carboxylic polymer and an amide

Amide functional ultraviolet light absorbers for polyolefins

A fluorescent yellow article containing a blend of an N,N'-disubstituted 3,4:9,10-perylenebis(dicarboximide) dye and a fluorescent yellow-green dye soluble in a polymeric matrix and meeting the chromaticity requirements of CIE and ASTM and having a fluorescence luminance factor of greater than 5, as well as a method of preparing such articles is described. Also described is a fluorescent retroreflective article containing a color layer having first and second sides, wherein the article includes retroreflective elements on one side of the color layer or a retroreflective base sheet disposed on one side of the color layer, where the color layer includes the above-mentioned fluorescent yellow article.
