wherein the alcohol aqueous solvent comprises a high molecular weight alcohol selected from the group consisting of 1-butanol, 3-methyl-1-butanol (isoamyl alcohol), 2-butanol, and hexanol and a low molecular weight alcohol selected from the group consisting of isopropanol, 1-propanol, and ethanol on wt-% basis in a ratio of from about 7:1 to about 10:1,
wherein the binder is selected from hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC), methyl cellulose, polyvinyl pyrrolidone, and sodium carboxymethylcellulose (NaCMC), and
