Claim 4
Dependent Claim
15 words
The method of claim 1, wherein said coating composition is an aqueous solution or suspension.
Claim 5
Dependent Claim
19 words
The method of claim 1, wherein said coating is about 3.5 milligrams per square inch of internal casing surface.
Claim 6
Dependent Claim
18 words
The method of claim 1, wherein said resin is curable from being water soluble to being water insoluble.
Claim 7
Dependent Claim
30 words
The method of claim 1, wherein said cellulose ether is selected from the group cosisting of non-ionic water soluble alkyl and hydroxyalkyl cellulose ethers, and anionic water soluble cellulose ethers.
Claim 8
Dependent Claim
32 words
The method of claim 1, wherein said cellulose ether is selected from the group consisting of methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, ethyl methyl cellulose, hydroxyethyl cellulose and ethyl hydroxyethyl cellulose.

Claim 14
Dependent Claim
16 words
The method of claim 1 wherein said coating composition is applied by spray shirring the casing.
Claim 15
Dependent Claim
28 words
The method of claim 1 wherein said coating composition is applied by slugging the casing with said cellulose ether and spray shirring the ether-coated casing with said resin.
Claim 16
Dependent Claim
25 words
The method of claim 1, wherein said cellulose ether is methyl cellulose and said resin is the reaction product of an epichlorohydrin and a polyamide.
