The results showed that there was a more better effect of filmformation and absorbency to use poly 1788 as an adhesive and polyvinyl pyrrolidone(K:90) as a hydrophilic polymer. The silicon dioxide with particle size 0.3-1 μm as a inorganic pigment had a better absorbency. The polyethylene glycol modified with ethylenediamine had a more better characteristic of dye immobilization, absorbency and definition than the polyethylene glycol modified with diethylenetriamine, of which the polyethylene glycol of molecular weight of 400 modifiedwith ethylenediamine had more best performance.
