An all-polymer grating microstructure device that exhibits a zero-order reflection under white light comprises a first polymer having a first refractive index and configured as a microstructure embedded within a second polymer having a second refractive index, each of the polymers of the first and second polymers at least translucent to white light with the proviso that the refractive index of the first polymer is at least 0.05 greater than the refractive index of the second polymer.

All-polymer grating microstructure

Two-layer receiver coatings particularly well adapted for use in inkjet printing comprise:

Durable multilayer inkjet recording media topcoat

Coating compositions for making ink jet recording media are disclosed which comprise a mixture of a binder composition comprising a non-cationic water-insoluble binder resin having a surface energy greater than 40 dyn/cm dissolved or dispersed in an alcoholic liquid medium or dispersed in an aqueous liquid medium, the liquid medium having a boiling point less than 150.degree. C. and a viscosity up to 100 kpa:s at 25.degree. C., and hydrophilic pigment particles having a number average particle size in the range from 1-25 microns and an oil absorption of at least 60 g oil/100 g particles, the composition having a pigment particle to binder resin weight ratio in the range from 0.5:1 to 3:1. A recording medium for ink jet printing is also described which may be made using this coating composition, along with a process for making it. A process for making a water-resistant color image on a support material using the described recording medium, along with the product obtainable by that process, is also disclosed. The color image has superior wear resistance and weatherability, making it well-suited for outdoor use.
