Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
24 words
An ink jet nozzle plate characterized by having a coating of a film which comprises a partially fluorinated alkyi silane and a perfluorinated alkane.
Claim 2
Dependent Claim
24 words
An ink jet nozzle plate characterized by having a coating of a film which comprises a partially fluorinated alkyi silane and a perfluorinated alkane.
Claim 3
Dependent Claim
20 words
A nozzle plate as claimed in claim 1 wherein there is an epitaxial gradation in the composition of the film.
Claim 4
Dependent Claim
87 words
A nozzle plate as claimed in claim 1 or 2, wherein the silane compound is distributed within the coating at a very high concentration in that portion of the coating which touches the plate and at a lower concentration in that portion of the coating away from the plate, and the alkane compound is distributed in the coating at a low concentration in that portion of the coating which touches the plate and at a high concentration in that portion of the coating away from the plate.
