PURPOSE:To provide an ink composition of high dryability, free from blur, etc., leading to clear printed image formation, resistant to development of cloggings, good in storage stability, suitable for ink jet recording, with the viscosity regulated in association with the dynamic surface tension. CONSTITUTION:The objective ink composition high in dryability even applied on paper of high sizing degree such as >=10sec of stocking sizing degree, capable of giving clear printed images free from blur etc., consisting of a composition satisfying the condition: [dynamic surface tension with a life of Omsec (dyne/ cm)]+[viscosity (cp)]=42-49. |
