Abstract:
A method for producing infra-red inert substrates, including molded polymeric articles, films, fibers and coatings and other organic and inorganic materials, by incorporating into the substrate or onto the surface of the substrate an effective amount of a dispersed bis-oxodihydroindolylen-benzodifuranone colorant. The thus obtained, also claimed substrates so produced are reflective and transparent to much of the near infra red radiation not reflected. There are multiple applications for cases of devices comprising electronic components, outdoor construction elements, outdoor furniture, automotive, marine or aerospace parts, laminates, artificial leather or textile materials, as well as in polychrome printing processes and optical fibers. The thus obtained substrates can also be subjected to laser welding. New bis-oxo-dihydroindolylen-benzodifuranone compounds are also claimed.
Abstract:
A pigment composition is provided comprising (a) an organic pigment and (b) an adduct containing a compound of formula (I) or a tautomeric form thereof, wherein X is O or S; Y is O, S or NR1; the group -A-B— is selected from the group consisting of —CR2═CR3—, —CR4R5—CR6R7— —CY—CR8R9—, —CX—NR10—, —CR11═N—, —CR12R13—NR14— and R1 is hydrogen, C1-C8alkyl, C3-C7cycloalkyl, C6-C10aryl or C7-C10aralkyl; R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 and R14 are independently of each other hydrogen, halogen, C1-C8alkyl, C2-C8alkenyl or C6-C10aryl, or R2 and R3 form a benzoannellated ring; and/or a melamine- or pyrimidine-based compound, which is optionally substituted. The pigment composition may be used as colorant in various applications, especially in coloring high molecular weight organic material, for example, coating compositions, paints, printing inks, liquid inks, plastics, films or fibers.
