The use of Escorez LC gives a better high temperature shear to eecorez like 5 found for Piccotac 95E but also gives the highest viscosity.

The catalyst for the polymerization is used in an 10 amount of 1.

Thirdly, aromatic modified aliphatic resins result in lower shear performance at higher temperatures in hot melt based pressure sensitive applications. Other cyclic dienes which are formed by co-dimerization of the cyclic dienes with C5 linear conjugated dienes or other reactive olefinic components in the petroleum feed stream, can also contribute esocrez a higher degree of cyclic structures in the final resin.

US USA en A hot melt pressure sensitive adhesive composition according to claims 6 to 9 which contains parts by weight of a petroleum-based aliphatic resin, parts by weight of a polymer and parts by weight of an extender oil. The reaction time is typically from 1. The components can be applied pure or diluted in an inert solvent like toluene or unreactive C4 to C6 components.

A typical composition of escirez used petroleum feed streams with and without cyclodiolefins and the plant recycled solvent is given below:. It is however found that feedstocks containing cycloolefinic and cyclodiolefinic components like cyclopentadiene and dicyclopentadiene contribute to more cyclic and rigid structures in the resins which eventually results in a better adhesive performance in a hot melt pressure sensitive formulation see example 3.

All resins mentioned herein were prepared in a continuous process, but a batch production would also be possible. A label comprising a substrate and a hot melt pressure sensitive composition comprising a polymer and a petroleum based aliphatic resin, wherein said petroleum-based aliphatic resin has: The peel strength is measured by a PSTC-1 test.

The subject-matter of the main request was considered not to be novel over the disclosures given in the documents D10, D23 and D The above polymer often is an S-I-S styrene-isoprene-styrene block copolymer having polystyrene and polyisoprene block segments. In the examples of the WO publication the values ” phr” or ” phr” were disclosed in conjunction with the specific tackifiers “E” and “Wingtack Extra”.

These deficiencies under Articles 84 and 83 could not be overcome by reference to the commercial product “Escorez ” escorex page 5, lines 29 to 31 of the patent specification, because no consistent characterization of this product existed in the prior art. D29 was therefore citable prior art. Futhermore, they impart excellent tack and shear properties on these hot melt compositions.

The patent, entitled “Low viscosity hot melt pressure sensitive adhesive compositions” was granted with thirteen claims, Claims 1, 9 and 10 reading as follows:. Auxiliary requests 1, 3 and 4 fscorez submitted rscorez the oral proceedings and auxiliary request 2 was filed with the letter dated 21 June Furthermore, a number of the requests did not overcome objections raised in the written proceedings or suffered from new deficiencies which had not previously arisen.

Esccorez the issues of admissibility of the Appellant’s requests and inventive step the Respondents argued as follows: They should therefore be admitted even at this late stage of the proceedings.

US 4, describes the use of aliphatic resins prepared as described in US 3, in S-I-S based hot melt pressure sensitive adhesives. Aromatic modified aliphatic hydrocarbon resins giving an excellent balance between tack and shear properties. Particularly preferred application forms are adhesive tapes and labels.

The Appellant’s arguments presented in the oral proceedings were as follows: Aliphatic resins petroleum-based method of controlling the softening point and the molecular weight, and pressure-sensitive hot melt adhesives containing them.

Thus obtained resins which are most suitable for use as tackifiers according to this invention have: Pressure sensitive adhesive compositions comprising rubber and a resinous interpolymer.

Admissibility of the Requests 2. The label of claim 16, wherein the hot melt pressure sensitive composition comprises: Furthermore, the first priority was without any doubt valid for the subject-matter of auxiliary requests 1 to 4 because component a of the adhesive composition was limited to specific embodiments which were indicated in the appli cation as filed and the first priority document as well.
