Esacure ONE by IGM Resins is a difunctional oligomeric alpha hydroxy ketone. It is a type I photoinitiator. Provides through and surface cure. Formula (1) was prepared using both Esacure M (A) and Esacure ONE (B). The results of the tests performed are reported in figures 1 & 2. Curing was. ONE offers very low odor levels and low migration but suffers from low solubility. A liquid version, Esacure ONE 75, is a 75% solution of ONE in 25% ethozylated.

The surfactant is e. At first a homogeneous solution is prepared by adding the photoinitiator at elevated temperatures to the surfactant. NL Ref legal event code: Examples of ether fluids are diethylene glycol dibutyl ether and phenoxyethanol.

After cooling, the pendulum hardness according to Koenig was measured. Most necessary For analysis and a reasonably well-functioning website.

HR Free format text: REF Ref document number: In esavure, especially with water-borne UV-curable paints, it is also very difficult to control the status of homogeneous dissolution as the paint formulation is in itself turbid. DK Free format text: Preferred are non-ionic surfactants having a poly alkylene oxide group, such as a poly- ethylene oxide group or a poly propylene oxide group or mixtures thereof.

These results show that the inventive liquid photoinitiator blends in addition to conventional non-aqueous UV systems, also give good curing performance in waterborne UV-paints. Other suitable polyols are polymers and copolymers containing hydroxyl groups in the polymer chain or in side groups, examples being polyvinyl alcohol and copolymers thereof or polyhydroxyalkyl methacrylates or copolymers thereof.

The alkoxylated surface active agent is responsible for the emulsifying properties and for providing compatibility of the resulting photoinitiator additive concentrate towards aqueous and non-aqueous formulations like paint or ink formulations. This solution is not suitable for aqueous systems.

LV Free format text: It is also used for powder coatings, food packaging, and clear lacquers for wood, plastic, paper, metal, and optical fibers. Solubilizing solid photo-initiators into the coating formulation may require excess or additional diluents that could adversely affect the properties of the coating or may be undesirable from environmental aspects.

Small amounts of water may not have a negative impact concerning the stability of the inventive photoinitiator blends as well as concerning the compatibility of the inventive photoinitiator blends for non-aqueous systems.

Suitable polyols are aromatic and, in particular, aliphatic and cycloaliphatic polyols. A1 Designated state s: The polyols may be partially or completely esterified with one carboxylic acid or with different unsaturated carboxylic acids, and in partial esters the free hydroxyl groups may be modified, for example etherified or esterified with other carboxylic acids.

The use of a homogeneous liquid blend according to claim 1 in the production of solvent-free, solvent- and water-based surface coatings, printing inks, screen-printing inks, offset-printing inks, flexographic-printing inks, resist materials or image-recording material. Preferably, the pure surfactant is a liquid at room temperature.
