Abstract
Described are an ink composition comprising water, a colorant and acrylic silicone resin particles having alkoxysilyl groups; and an image recording method comprising discharging the droplet of an ink composition from a recording head to record an image on a substrate, wherein an ink composition comprising water, a colorant and acrylic silicone resin particles having alkoxysilyl groups is used as the ink composition. According to the present invention, 1) blotting of the ink composition on the substrate can be prevented, 2) an image which has water resistance and has a markedly high image density can be obtained, 3) an image does not become sticky even under a high environmental temperature, and 4) there is no problem in safety.
Claims22
An ink composition comprising water, a colorant and from 1 wt. % to 50 wt. % of acrylic silicone resin particles having alkoxysilyl groups, wherein the alkoxy group of said alkoxysilyl group has 1-3 carbon atoms and said acrylic silicone resin has a weight-average molecular weight of from 2,000 to 100,000.
An ink composition which comprises water, a colorant and acrylic silicone resin particles having a C.sub.1-3 alkoxysilyl group, the content of said particles being from 1 wt. % to 50 wt. %, wherein said acrylic silicone resin has a weight-average molecular weight of from 2,000 to 100,000.
An ink composition comprising water, a colorant and from 1 wt. % to 50 wt. % of acrylic silicone resin particles having an alkoxysilyl group, wherein said alkoxysilyl group is represented by formula --Si(OR).sub.3 where R represents a C.sub.1-3 alkyl group and wherein said acrylic silicone resin has a weight-average molecular weight of from 2,000 to 100,000.
An image recording method comprising discharging the droplet of an ink composition from a recording head to record an image on a substrate, said ink composition comprising water, a colorant and from 1 wt. % to 50 wt. % of acrylic silicone resin particles having alkoxysilyl groups, wherein the alkoxy group of said alkoxysilyl group has 1-3 carbon atoms and said acrylic silicone resin has a weight-average molecular weight of from 2,000 to 100.000.
