USES AND APPLICATIONS 
Pigment Green 7 is used as raw material for 
PAINT, INK, TEXTILE EMULSIONS and as colourant for PLASTICS RUBBER  SOAP, etc. 

PAINT : Pigment Green 7  has  wide applications  in all  types of paints,exterior paints  and enamels, lacquers, emulsion paints of   various  types,  automotive  finishes  and  bakingenamels. It  has excellent  fastness to exterior exposure either full strength or as pastel shades.lt is valuable colour for preparing "Universal tinting Pastes". The soft texture of Phthalocyanine pigment renders its applications in paints as very facile. 

PRINTING INK :Pigment  Green 7  is excellent  in soap resistance, detergent resistance, acid resistance and alkali resistance.lt is highly suitable  in  use  with  organic  solvents  and  has high  light  fastness properties. lt  is used  in manufacturing all kinds of printing inks such as publication inks, metal lithography inks, flexographic and gravure inks, lithography inks, ink for food wrappers and soap wrappers, etc.. 

TEXTILE : Textile printing inks are well known for producing artistic designs  on textiles. Phthalocyanine finds a good contribution  in this field. Phthalocyanine printing emulsions with appropriate binders are important  applications of this group  of pigments  Spindyeing of PVC fibres, viscose, cuproammonium cellulose nylon, Perlon L and Risan are other important applications. 

PLASTICS : For plastics  the pigment  must  be  very fine particle size and ability to disperse evenly in the material. All these are achieved in case of Phthalocyanine pigment. 

RUBBER:Rubber goods are increasingly been coloured. Tile presence or  copper in Phthalocyanine has no effect on the ageing of Rubber. 

MISCELLANEOUS COLOURANT APPLICATIONS :  Pigment  Green  7  is used extensively for colouring  roofing granules because of its high light fastness under exposed conditions. It can also be used for colouring cement for exterior painting of buildings.
