1. a shadow mask type PDP is used lead-less photosensitive transparent medium slurry, it is characterized in that this slurry consists of:

  • lead-free glass powder 50~

    85%, photosensitive monomer 3~


    Light trigger 0.3~

    5%, organic solvent 5~

    20%, celluosic resin 5~


    Softening agent 1~

    2%, tensio-active agent 1~


    On address following ratio all in wt%;

    Said lead-free glass powder consists of;

    Bi 2O 345%~

    80%, SiO 24~

    25%, B 2O 310~

    30%, ZnO 2~

    10%, and the palladium powder particle diameter requires 0.8~

    1.2 μ


    Said photosensitive monomer uses the double pentaerythritol C5 methacrylate of propenoate or methyl acrylic ester, double pentaerythritol methacrylate, one or more in 1,6 hexanediyl ester or the pentaerythritol triacrylate.Said light trigger is st-yrax and verivate thereof, methyl phenyl ketone and verivate thereof, and the 1-of aromatic ketone compounds class is to morpholinyl phenyl-2-dimethylamino-2-benzyl-1-butanone, one or more in Alpha-hydroxy cyclohexyl-phenyl ketone or the st-yrax dme;

    Organic solvent is a boiling point at the polar organic solvent more than 200 ℃


    one or more in diethylene glycol monobutyl ether, Terpineol 350, Viscotrol C, phenylcarbinol or the tributyl citrate;

    Said macromolecule resin is a celluosic resin;

    The preparation organic carrier;

    take by weighing said macromolecule resin, organic solvent, tensio-active agent, coupling agent and add a plasticiser component in beaker by proportioning, 90 ℃

    of heating in water-bath are constantly stirred, and use silk screen filter up to resin dissolves and cooling back;

    The viscosity controller that makes organic carrier is in 100~

    300Pas scope;

    Slurry modulation;

    with lead-free glass powder, photosensitive monomer, light trigger, organic carrier according to the above ratio dispersing and mixing evenly after, carry out three-roll rolling.
