The  material  is intended for interior  use.  The  specification applies to sheets in which the only filter is paper and does  not cover  sheets with a core of any other material covered  by  this report  is not intended for load beariong applications. In  India three  types of decorative and industrial  laminated  sheets or products are being  manufactured usually using phenol formaldehyde or melamine formaldehyde or other phenolic resins as bindiong  materials  for  the core and the  surface  papers.  The decorative  paper  for  lamination is imported.  The  laminated products are assuming increasing popularity for table tops, sink tops, other decorative articles as also in electrical  appliance. Mica  coated  or satin papers are a special type  of  fancy and decorative  sheets  whose  surface glisters  and  sparkless with thousands of tiny reflections of light. The sheet is produced in a  wide range of colours and may be printed or embosed  at  will. The most popular colours are the postal and light shades and they are  used in the fancy box and packaging field, for  labels,  and for various other decorative applications. The  sparkling  effect  is  obtained  by  suspending  finally ground mica flakes  in  the coating  mix and these orient themselves in  the coating when it is laid down on the paper so  that  their reflecting surfaces are parallel  to the surface of the sheet with the result  that  they act  as countless tiny mirrors which  reflect the light. Mica is usually the only  pigment  used  in  these formulations as it  is  not desirable to cover the  brilliance  in  any  way.  No coloured pigments or pulp coloured pigments or  pulp colours  for a similar reasons, but dyestuffs are commonly used to attain  the desired shade.
