The present invention provides a method for printing high opacity images or coatings using solvent based inks comprising hollow polymeric microspheres, wherein the inks do not contain titanium dioxide. The International Agency for Research on Cancer (IARC) has classified titanium dioxide as “possibly carcinogenic to humans,” The method of the present invention allows one to avoid the use of inks that rely on titanium oxide for high opacity, which has become of importance for articles that come into contact with one's mouth, for example, cigarette tipping papers.

An interlayer material for a lithium-sulfur battery, and a lithium-sulfur battery, the interlayer material including electrically conductive MOF modified carbon fiber paper material between the separator and cathode accelerating electron transfer and having catalytic and barrier effect on lithium polysulfides. The paper material is prepared by: pretreatment of the paper by subjecting the carbon fiber paper to hydrophilic treatment; preparation of carbon fiber paper grown with Co.sub.3(HITP).sub.2 including: complexing Co.sup.2+ and hexaiminotriphenylene on the paper surface, and allowing the product to grow in situ; and removal of structural impurities. The carbon fiber paper provides an electrically conductive substrate ensuring high-speed electrode movement between the cathode and separator; and Co.sub.3(HITP).sub.2 grown on the carbon fiber paper provides sufficient polarity for the adsorption of lithium polysulfides, alleviating the shortcomings of the carbon material, and promotes a lithium polysulfides reaction through the catalysis of Co—N.sub.4, inhibiting the shuttle effect of the polysulfides.
