Appeal No. 2005-1402 2
Application No. 10/403,021
of high speed and high resolution with a laser beam, and a method for forming a multicolor
image. Claims 1, 3 and 4 are illustrative and read as follows:
1. A multicolor image-forming material comprising:
an image-receiving sheet comprising a support and an image-
receiving layer; and
at least four thermal transfer sheets each comprising a support, a
light-to-heat converting layer and an image-forming layer, the at least four
thermal transfer sheets comprising yellow, magenta, cyan and black thermal
transfer sheets,
wherein image-recording is performed by the method comprising the
steps of:
superposing each one of the at least four thermal transfer sheets on
the image-receiving sheet to be in a state of the image-forming layer being in
contact with the image-receiving layer; and
irradiating the thermal transfer sheet with laser beams in two-
dimensional array to transfer an image in an area of the image-forming layer
subjected to irradiation onto the image-receiving layer, and
a recording area of a multicolor image in each of the thermal transfer
sheets is a size of 515 mm x 728 mm or more, a resolution of the transferred
image is 2,400 dpi or more, and each of the light-to-heat converting layers
comprises from 9.2 to 20 % by weight of a substance which is liquid at 30°C.
3. The multicolor image-forming material according to claim 1,
wherein the substance has a solubility in water of 10 g or more.
4. The multicolor image-forming material according to claim 2,
wherein the substance has a solubility in water of 10 g or more.
The sole issue in this appeal is whether the examiner properly rejected claims 3 and
4 under 35 U.S.C. § 112, second paragraph, as being indefinite for failing to particularly
point out and distinctly claim the subject matter which appellants regard as the invention.
