Primer for digital printing
The present invention is directed to primer coatings that enhance the adhesion of liquid digital printing inks and toners to the substrate. The coatings comprise one or more polyurethane dispersions and one or more acrylic emulsions. The coatings of the present invention improve resistance to mineral oils, such as those typically found in liquid digital printing inks and toners. The primer coatings of the invention also reduce blocking, so that a primer coated reel of substrate may be easily unrolled, even after having been stored in the rolled reel for an extended period of time.
PHOTO-RESPONSIVE SHAPE CHANGING POLYMER COMPOSITION FOR COLORED OPTICAL LENS
Photo-responsive shape changing polymer compositions including photoinitiators that absorb light in the range about 400 nm to about 700 nm, a cross-linked polymer matrix and a polymerizable composition. Photopolymerization of the polymerizable composition sorbed in the cross-linked polymer matrix results in the shape change which manifests in the change in the refractive properties of the composition. The light dose required to effect the shape change; lock-in dose and the photobleaching dose are determined by the choice of the photoinitiator, electron donor and the hydrogen donor. These compositions are useful in the fabrication of coloured lenses, especially intraocular lenses.
THERMALLY CONDUCTIVE ELECTRICAL INSULATION MATERIAL
A thermally conductive, electrical insulating nonwoven material is described that comprises 20 wt. %-50 wt. % organic components, wherein the organic components comprise wherein the organic components comprise organic drawn fibers, organic bi-component binder fibers, and a polymer latex binder comprising at least one of an acrylic latex, an acrylic copolymer latex, a nitrile latex, and a styrene latex; and 50 wt. %-80 wt. % inorganic components wherein the inorganic components comprise a blend of thermally conductive fillers and clay. The organic bi-component binder fibers have a polymeric core and a sheath layer surrounding the polymeric core wherein the sheath layer has a lower melting point than the core.
