PURPOSE:To obtain a support capable of obtaining planographic printing plate good in dimensional stability, excellent printing durability and reduced in the change of photographic properties due to a humidity and temp. condition, by forming the same from PE double-sided coating paper coated with a mixture consisting specific low density PE and high density PE. CONSTITUTION:Both surfaces of raw paper are coated with a mixture consisting of 10-90wt% of low density PE (A) with density of 0.915-0.935g/cc and melt index (MI) of 1.0-30g/10min and 90-10wt% of high density PE (B) with density of 0.940-0.970g/cc and MI of 1.0-30g/10min to obtain an objective support with volume electric resistance of 10<10>OMEGA or less. |
